I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon in Feb 2018
Interview
The Hiring manager contacted me on LinkedIn. The team seemed really excited by my profile and I had the first round of interview with the team lead. It was purely ML based questions and I was able to answer them all. For the second round they send me an online coding challenge, which didn't relate to ML, was more about datastructues and algorithms. I did decent on that challenge but didn't get a call for the next interview round.
I was assuming they would give more weightage to my ML skills rather than some optimizations I might have missed on coding challenge and was pretty disappointed to not hear back.
Interview questions [1]
Question 1
Bias-variance, Overfitting, and some other basic ML concepts
Some problems related to transfer learning
Some problems related to scaling the algorithm
The interview process was smooth, and the interviewer was professional and friendly. It was online and took about 35 minutes. The recruiter will give you some guidelines on how to prepare.
Only had first round, a recruiter reached out to me as I had applied for another role. the total time to interview was 2 weeks. One recruiter interview and then with the hiring manager

Question 1
Low level system design about designing a ranking system based on the number of sales of a product as well as taking into consideration the time complexity. had to do some in O(logn)
HR call followed by a 1-hour coding interview with a team member. Then, a loop consisting of 5 rounds: 2 LeetCode-style coding interviews, 2 system design interviews, and 1 behavioral interview

Question 1
LeetCode questions are at the easy/medium level. System design is a regular task about designing ML algorithms
