Hello hello, this is Jordan from SnapStack Solutions, coming to you again with some fresh energy in the new year. I hope you enjoyed the holidays with your closest ones. On behalf of my entire team, I wish you a peaceful mind, a harmonious home, and a successful year! 🙂

I will kick this new year off with some fresh content, but still in a way connected to the previous articles. Just for a reference, last month we talked about the importance of R in data science. As always, I am here to remind you to check it out if you didn’t have the chance to read it. Follow this link here.

Still, I want to cover more on Big data tools, and today I’ll go with three of them that are under the Apache Software Foundation. For those of you who are curious about Apache, it is a nonprofit corporate corporation that supports Apache software projects. It was March 1999, when ASF was initially formed.

However, you may search for yourself more on this topic, while I, on the other hand, will try to cover three Apache technologies, and those are: Spark, Hive, Hadoop.

Let’s see what are they used for, and how important are they for the Big Data as a whole.

Apache Spark

The first one-off is Apache Spark. Most of you may already heard of it, but let’s learn more about this technology. For starters, it is an open-source analytics engine used for big data workloads.

It was born in 2009 at the University of California, Berkeley, while the ones developing it tried to find a way to accelerate the processing jobs in Hadoop Systems.

It is based on Hadoop MapReduce and it provides native bindings for programming languages such as Python, Scala, Java, and R. I cannot go through but to also mention the libraries it includes for Machine Learning – Mllib, stream processing – Spark Streaming, and graph processing – GraphX.

In order to minimize the complexity of the data, the Spark Core Engine is using RDD r Resilient Distributed Dataset. It works in a way that data and partitions are aggregated through a server cluster, where it is handled and stored in another data store, or run through an analytic model.

Benefits of Apache Spark

Speed – Probably the most valuable thing nowadays. The reason why Spark is standing out from the others is that it uses its in-memory engine, making it 100 times faster than MapReduce when ran in-memory and 10 times faster when processed on disk.

Real-time stream – This technology can work with real-time streaming together with the integration of different frameworks.

Many workloads – Spark is able to work with several workloads, such as interactive queries, real-time analytics, machine learning, and graph processing.

Apache Hadoop

Hadoop is another tool that is really important when it comes to this field. It is a collection of open-source software utilities that are made to do computing on a massive amount of data. It processes structured and unstructured data in order to collect, process, and analyze big data.

Just like the previous technology, we will go through the advantages of using Apache Hadoop.

Benefits of Apache Hadoop

Cost-effective – This technology is coming forward with a cost-effective storage solution for massive data sets. In the past, companies would have down-sampled the data and classify it based on different assumptions, just so they can avoid the costs, leaving them with deleted raw data, that afterward would be valuable.

Scalable – Hadoop is a very scalable storage platform and when it comes to storing, it can distribute massive data sets on many cost-efficient servers that work in parallel. It gives the companies the opportunity to handle applications on thousands of nodes, together with thousands of terabytes of data.

Flexible – Companies can use Hadoop to derive valuable analytics from platforms like social media and email conversions. In addition, it can be used for many other activities, like log processing, data warehousing, market campaign analysis, and fraud detection.

Apache Hive

As we are talking about the Hadoop Platform, it is inevitable to mention Hive. So what exactly is Apache Hive?

It is a data warehouse system that is used to summarize, analyze and query massive amounts of data. To better understand this, SQL queries are transformed into different forms, like MapReduce so the activities are reduced to a bigger extent.

Apart from this, the Hive also gives the data a structure that can be stored in a database, so the users can connect to Hive while using a command-line tool or JDBC driver.

Benefits of Apache Hive

Better productivity – This technology is designed for summarizing, querying, and analyzing data. It works for a big range of functions that are interconnected with Hadoop packages like Rhipe, Apache Mahout, and many others.

Cleaner working – Hive includes cleansing, transforming, and modeling data to provide valuable information about different business insights which in the end, benefits the company.

User-friendly – Hive gives the users the opportunity to access the data and increase the response time at the same time. In comparison to other tools, Hive’s response time is way faster.

All in all, we have gone through the basics of these technologies and their advantages. In the world of handling big data, they are playing a crucial part. Of course, there is so much to be said about this, as it is a wide topic, but I’ve tried to bring it closer to you.

Our big data specialists would be more than glad to answer any question you might have. Feel free to check out our social media and get in touch with us. Until next time. 🙂

The shift towards skills-based hiring: A new era of talent acquisition

In today’s fast-evolving job market, there’s a growing trend towards skills-based hiring, which places a stronger focus on a candidate’s practical abilities rather than traditional qualifications like degrees or titles. This shift is fundamentally changing how companies approach recruitment, resulting in more dynamic and diverse workforces.

Organizations are increasingly recognizing that skills-based hiring can lead to better job performance, role fit, and inclusivity, which is driving widespread adoption of this model.

What is skills-based hiring?

Skills-based hiring is a recruitment strategy where employers focus on a candidate’s specific skills and competencies rather than their formal education or past job titles. For instance, companies may prioritize technical skills, such as proficiency in certain programming languages or software, or soft skills like communication and problem-solving, over traditional criteria like a four-year degree. As noted by SHL, this approach allows companies to uncover hidden talent and focus on candidates’ potential, helping organizations foster diversity, equity, and inclusion.

Why skills-based hiring is gaining popularity

  1. Access to a wider talent pool
    Traditional hiring methods often exclude individuals who may not have formal degrees but possess valuable skills. By adopting skills-based hiring, companies can tap into non-traditional talent pools, including self-taught professionals and those from different socio-economic backgrounds. As Workable reports, nearly 45% of companies in 2024 are expected to drop degree requirements for many roles.
  2. Improved role fit and performance
    Skills-based hiring often leads to a better match between the candidate and the job. Focusing on specific, measurable skills means that employees are more likely to succeed in their roles from day one. According to BCG, hiring based on skills is five times more likely to predict job performance than hiring based solely on degrees. By assessing candidates based on real-world competencies, employers can ensure a higher level of job readiness and productivity.
  3. Fostering lifelong learning and agility
    As companies face rapid technological changes, employees need to continuously upskill to remain relevant. A skills-based approach promotes a culture of lifelong learning, encouraging employees to focus on acquiring new competencies rather than relying on outdated credentials. This mindset aligns with the needs of industries such as IT and digital marketing, where practical skills and staying current with trends are crucial .
  4. Reducing bias and increasing diversity
    Traditional hiring processes can unintentionally reinforce biases related to education or socio-economic background. By shifting the focus to skills, companies can reduce these biases, offering more opportunities to underrepresented groups. According to SHL, a skills-based model promotes inclusivity by leveling the playing field, making it easier for companies to create a diverse workforce.

The challenges of implementing skills-based hiring

While the benefits of this approach are clear, there are several challenges that companies must navigate when adopting skills-based hiring practices.

  1. Defining clear skills criteria
    One of the main challenges is defining the precise skills required for each role. Companies must shift from focusing on traditional job descriptions to crafting skills-based profiles that clearly outline the necessary competencies.
  2. Effective skills assessment
    Assessing a candidate’s skills is often more complex than verifying their educational background. Companies must rely on practical assessments, such as tests or simulations, to evaluate real-world capabilities. For example, Boeing created an apprenticeship program for cybersecurity roles that doesn’t require a degree but emphasizes hands-on learning and skill development (
    McKinsey & Company) (BCG Global).
  3. Cultural change within organizations
    Shifting from a qualifications-based hiring approach to one focused on skills may require a significant cultural change. Long-standing hiring practices can be difficult to overhaul, and companies must invest in training hiring managers and redesigning recruitment processes to fully embrace skills-based assessments.

How companies can make the shift

  1. Invest in skills assessment tools
    Organizations need reliable tools to accurately assess candidates’ skills. Platforms offering practical evaluations, coding challenges, or case studies can help measure relevant abilities in a fair and transparent manner. As SHL highlights, using data-driven assessments allows companies to objectively evaluate competencies, improving hiring outcomes.
  2. Promote upskilling and internal mobility
    Fostering a culture of continuous learning is essential for the future workforce. Companies that encourage employees to reskill and grow within the organization can fill talent gaps internally. BCG notes that employees hired through skills-based hiring often experience longer tenures and are promoted at rates similar to those hired based on degrees.

How do we see it?

The shift toward skills-based hiring is more than just a trend; it represents a fundamental change in how organizations view talent acquisition. As businesses prioritize practical skills and competencies over traditional qualifications, they can build more dynamic, diverse, and high-performing teams. While there are challenges, including defining clear skills criteria and developing effective assessments, the long-term benefits of this approach make it a valuable strategy for future-proofing the workforce.

This approach is not only more inclusive and adaptable but also positions companies to better meet the demands of a rapidly changing job market. As SHL, BCG, McKinsey&Company and other industry leaders have demonstrated, skills-based hiring is key to unlocking hidden talent and ensuring long-term organizational success (McKinsey & Company).

Streamline your recruitment efforts with RPO: The key to efficiency and cost-effectiveness

Are you struggling to manage your recruitment processes effectively? If so, Recruitment Process Outsourcing (RPO) could be the solution you need. RPO is a preferred method for many companies due to its numerous advantages in optimizing recruitment and enhancing efficiency. This approach not only helps in acquiring new employees but also offers a comprehensive understanding of your company's operations and builds strong relationships with hiring managers.

What is Recruitment Process Outsourcing (RPO)?

Recruitment Process Outsourcing (RPO) is a strategic partnership where an external provider manages part or all of the recruitment process for a company. Unlike traditional recruitment, RPO involves a deeper integration with the company's teams, leading to a more efficient and streamlined process. Here’s why RPO stands out:

Direct access and quick feedback

In a traditional recruitment setup, recruiters often face communication discrepancies and delays when dealing with multiple hiring managers. They might be dismissed with vague responses like "I don't have time now," which hampers their efficiency. With RPO, you'll have direct access to hiring teams and can address their needs promptly. This leads to:

  • Reduced delays in candidate evaluation.
  • Quick and precise feedback on potential hires.
  • Efficient recruitment process with fewer obstacles.

Added value and efficiency

One of the main advantages of RPO is the added value it provides. RPO recruiters work closely with hiring managers to understand their specific needs and requirements. This results in:

  • Reduced time-to-fill vacant positions.
  • Increased efficiency in candidate selection.
  • Improved accuracy in hiring decisions.

Financial benefits

From a financial perspective, RPO can be more cost-effective compared to traditional recruitment methods. The cost benefits include:

  • Reduced recruitment costs due to streamlined processes.
  • Lower time-to-hire, which saves money.
  • Cost comparison data in our presentation (see slide no. 4) illustrates the percentage by which RPO can be cheaper than traditional methods.

Additional benefits of Recruitment Process Outsourcing (RPO)

RPO offers several other benefits that contribute to overall recruitment success:

  • Saves time for your internal team by handling the recruitment process and communication.
  • Eliminates the need for an internal recruiter.
  • Assists in setting up efficient recruitment processes.
  • Trains team leaders to enhance recruitment practices.
  • High motivation from RPO recruiters to make successful placements.
  • Improved candidate experience, as candidates interact with a dedicated representative rather than multiple agencies.
  • Enhanced market impression with a single point of contact for candidates.

Conclusion

If you want to recruit efficiently, reduce costs, and enhance your company's competitive edge in the coming year, consider adopting Recruitment Process Outsourcing (RPO). This strategy not only streamlines the recruitment process but also brings significant financial and operational benefits.
