I applied online. The process took 2 months. I interviewed at Amazon (Palo Alto, CA) in May 2017
Interview
I applied online (Machine Learning Scientist at AWS) and contacted by a recruiter after a month or so. Technical phone screening is scheduled subsequently for one week after. In the meantime, I studied for Machine Learning, Probability & Statistics, Programming questions.
The interviewer was a nice person, but was a bit confused himself; and sometimes was not so clear in his questions. The questions were all Machine Learning questions, no Statistics/Probability, or Programming (even though there was a shared screen for coding).
He asked about a project I've done on Machine Learning and questions mostly evolved from my answers (careful about what you say!): the difficulty level mostly depends on the knowledge you already have.
The questions were overall easy and conceptual, and required a general knowledge on various topics.
Interview questions [4]
Question 1
Difference between convex and non-convex cost function; what does it mean when a cost function is non-convex?
Call with a recruiter followed by technical interview. The technical interview covered broad Machine learning questions. Then the coding part. The problem required prior knowledge of a calculus theorem, which in my opinion was not fair.
the interview process was nice and clear. Had two rounds of interview for the internship position. Both rounds were technical interviews. They asked my research experience and a case-study. Both had programming questions
I applied online. I interviewed at Amazon in Jan 2021
Interview
The interview process is very structured and clearly explained. The decision making on the employer's side was quite fast.
The only negative factor during the interview process was that no one showed up for my first scheduled interview.
