J'ai postulé en ligne. J'ai passé un entretien chez Visa Inc. (Austin, TX) en déc. 2019
Entretien
Hackerrank with 3 questions -> hiring manager interview -> interview with 4 engineers on the team. Then another interview with the hiring manager that's basically there to sell you on the company if you pass their interviews.
Questions d'entretien [1]
Question 1
1) Design Uber (what services would make it up, how to scale it, tech you have used before that would be applicable)
2) standard Min Heap question from leetcode
3) implement a queue with 2 stacks
3) write an algorithm to traverse a graph similar to google maps with both dfs and bfs and list the pros and cons of both. Also how would you optimize the speed at which the api call is made from client to server (caching, fragmenting DB, using LTM, graphs are served on a region by region basis, etc)
Had two technical interviews, back to back. Medium leet code problems. Not that hard. After received an email that they did not proceed with me, but had other manager internally interested in my profile
First round OA
Second round interview in which I was given a dp question and then asked about my projects in detailing then we move to some oops and language based questions
J'ai passé un entretien chez Visa Inc. (Stockholm, )
Entretien
The interview process started with a coding test from Hackerrank with 2 easy and 1 intermediate question. I found the questions to be rather difficult given that you are not allowed to use google or check syntax.
