I applied through an employee referral. The process took 4 weeks. I interviewed at integrate.ai (Toronto, ON) in Apr 2017
Interview
The interview was pretty intense. First round was a phone interview, which surprisingly had a coding challenge. A current Machine Learning Scientist sent over a dataset, and basically asked me to do a quick modelling pipeline with that data. I had to explain my thoughts and reasoning to her while I am typing the code.
The second round was on-site with 5 back-to-back sessions. Three technical sessions and two culture sessions. The technical sessions were pretty comprehensive. They each tested for the knowledges in ML, the ability to model the practical problems, and the coding ability. The interview questions are challenging, but the interviewers are generally pretty nice.

Question 1
One question they asked for the culture session was to describe a previous experience on how to deal with the disagreement with other colleagues.
It was a skype call where I was asked to problem solve various real life data science scenarios. Then I was shown a spreadsheet and asked how I would go about analyzing it and to code up my solution.

Extract data from a spreadsheet and do a linear regression.
I applied online. The process took 3 weeks. I interviewed at integrate.ai (Toronto, ON) in Sep 2017
Interview
The interview process was thorough:
- 1 phone interview with talent lead
- 2 technical skills interviews with 2 engineers (one of which consisted of whiteboarding pseudo code, and talking mostly about past experiences)
- 2 values interviews, which was mainly about the assessment of my own values and how they may or may not be in line with the company's values
After the formal interviews, I was invited to attend a couple of the meetups organized by the integrate, namely "AI in the 6ix". While this should probably be considered as another interview, I enjoyed attending these meetups as it gave me the opportunity to talk to more members of the team as well as a glimpse into the company culture.
