I applied through university. The process took 2 months. I interviewed at X in Feb 2015
Interview
Firstly applied for Software Engineer Intern because they said they will not have Data Scientist Intern this year.
1. Online code challenge (easy).
2. 45-minute on-campus interview about previous CS projects, a white-board coding problem.
Then they reassigned me to the "non-existing" Data Scientist Intern application after this round.
3. 45-minute phone interview about a dynamical programming question, plus some brain storms about user modeling.
4. 3 45-minute on-site interviews of a composition of coding, stats, machine learning, algorithm and previous experience.
5. Got the offer.
The recruiter got in touch to set up a screening call. I was asked basic questions concerning my background and my motivation. Then we had a coding challenge with a question I later found on LeetCode under the Twitter section for the last 6 months.
Case study was interesting; interviewer was previously from uber so some similar interview questions, techniques do apply, overall a good engaging exercise. Nothing to complain about. Overall it is okay
