The hiring manager sent me the Practical Test for the wrong position. Didn't find out until I got called for a phone interview. Extremely adversarial interview. I was asked about a past project, and to describe the methodology that I used. As I tried to explain, the interviewer constantly interjected, condescendingly questioning why I did this or that. He then asks me to change gears, and to think deeply and mathematically about a methodology with which I am most familiar. I state my method -- and expecting a deep mathematical question about it, he hits me with a high-level question, which I don't answer quickly enough for his tastes. He accuses me of not answering any of his questions, being "more academic than practical" and abruptly terminates the interview. Didn't hear one word about the job itself.

I applied online on the website. I received an email from the Director of Data Science himself. He gave me a short test to complete. I did not complete the entire hiring process due to personal circumstances. Even so, the director invited me for a coffee and we chatted. He was very friendly and was keen on sharing his passion about the company and Data Science. I was very impressed. If it weren’t for my personal circumstances, I would have finished the process.
