3 Things to Look for in a Big Data Candidate
Well-rounded big data candidates need to do more than just demonstrate mastery in the big data and data science field. To be successful, they should have the right type of attitude, outlook, and personality as well. Here are three characteristics to look for among your big data candidates.
- Drive – Success in big data and data science takes commitment, drive, and perseverance. Just having the skills may not be enough, candidates also need to be committed and dedicated to achieving results no matter what. One key identifier of (driven?) candidates with drive is self-training. Whether evidenced through online course participation or forum activity, it’s hard to go wrong with professionals who demonstrate the drive to teach themselves what they need to know for success.
- Personality – As any good HR Specialist will advise you, it’s important to hire people who are friendly and personable. No one wants to work with an over-competitive, unapproachable jerk; No matter how smart they are. When hiring big data professionals, look for people who love their field so much that they are willing to share and give back on their own time. Forms of “giving back” might include open source contributions, forum participation or data volunteerism for social good.
- Skills and Experience – It’s no news that there is an extreme shortage of professionals with experience and skills working in big data and data science. Even where experience may be lacking, if you can find big data candidates with prestigious training credential(s), you might want to give them a second look.
