I applied online. The process took 4 weeks. I interviewed at Unit8
Interview
Thorough yet very enjoyable 4-step interview process:
– Online HackerRank assignment: 3 problems, overall medium difficulty.
– Informal interview with HR and an engineer. General introduction, opportunity to learn more about the job / company.
– Technical interview 1 (coding). Two problems, one very simple and one more involved.
– Technical interview 2 (data science). The first part of the interview required to write an SQL query and implement an algorithm to solve a problem (the algorithm was given). The second part of the interview tested knowledge of various ML topics. No trick questions as long as you know the fundamentals well.
Great experience overall!
