Me postulé en línea. El proceso tomó 2 meses. Acudí a una entrevista en Amazon (Estambul) en nov 2019
Entrevista
1) HR interview
2) Phone interview with engineer
3) Virtual onsite interview (5 sessions)
They have too many gotchas ("culture") to learn: 14 principles, shareholder letters, ceo's bio, a first dog in the office (died years ago), this and that...
I practiced for weeks before phone interview. Then i practiced for few more weeks before virtual onsite interview.
Preguntas de entrevista [1]
Pregunta 1
Phone interview:
1) What data structure would you use to represent building and doors
2) How would you find shortest path from any room to exit?
Virtual onsite interview:
1) Implement Unix find utility as a library API
- Inputs: Starting folder and user defined criteria to match lets start with a) name pattern and b) max size threshold
- Output: List of files matching the given criteria
- Looking for design of abstractions (inputs), implementation of the API itself and sample usage
2) Given a list of strings, determine if they are isomorphic and group them by isomorphism. Two strings X and Y are called isomorphic if all occurrences of each character in X can be replaced with another character to get Y and vice-versa. Consider the strings “ACAB” and “XCXY”. They are isomorphic as we can map ‘A’ -> ‘X’, ‘B’ -> ‘Y’ and ‘C’ → ‘C’. Mapping from a character to itself is allowed but two different characters may not be replaced by the same character.
3) Find the Balance point of an Array
// [3, -2, 0, 4, 6, -5] -> [3]
4) behavioral questions (actual interviewer didn't show up)
5) Mobile System Design
Initial screening call with recruiter followed by a 1 hr hacker rank question on DSA. The final round was a panel consisting of 4 interviews ranging from technical design, more DSA and behaviour questions.

Describe a time when you disagreed with your team and how you resolved it
Online Application & Assessment: Candidates apply via amazon.jobs and may be asked to complete online assessments (work simulations or technical tests).

Bar Raiser Interview: One interviewer is a "Bar Raiser," a neutral employee from another team tasked with ensuring hiring standards remain high.
Hiring Committee/Debrief: Interviewers meet to discuss candidate feedback and make a hiring decision.
Recruiter screen. Then 2 coding interviews then onsite rounds (another coding question, then a system design question, then HM behavioral interview). System design was simpler than other companies. Coding was leetcode ish
