Initial phone screen -> Short technical interview over the phone/shared Python notebook -> Onsite interview (I had to prepare and present a short presentation on the topic of my choice + 2 technical interviews + 1 chat with the Head of Data Science)
I applied through an employee referral. The process took 1 week. I interviewed at Kik (Waterloo, ON)
Interview
It was well organized and pleasant. I asked a friend of mine to refer it to a mutual friend who works there. I got a call from HR and then she gave a statistics question after that there was a kaggle sort of peer coding challenge online with Manager. After this, I was called on-site for a 4 round interview. 1st one was a probability and stat interview which was pretty challenging. The second one was a python programming interview. It was some web log parsing. Nothing hard. 3rd one was SQL and programming again with the Hiring Manager which was a bit hard but manageable. The final one was with Engineering Manager which was more like a cultural fit.
I applied online. The process took 4 weeks. I interviewed at Kik (Waterloo, ON) in Nov 2017
Interview
1) phone call with HR
2 ) phone call for technical questions
3) x3 in-person interviews.
The in-person was pseudocoding and probability questions. I found for one of my panel interviews the two interviewers kept going back and forth, not even giving me the chance to talk. For the same set of interviewers, I found that they didn't check out my GitHub account before the interview. Before I could explain my model and methodology, the two people kept talking over me.
I would have preferred a take home test after the 2nd phone call than answer probability and coding questions on the spot. I guess I should have done more problems on LeetCode
