I applied through college or university. I interviewed at Visa Inc.
Interview
All behavioral questions from these 2 guys except for one technical question, which was to implement a hashtable. I do that using the method my university teaches me, to which one interviewer said good but the other is like wait you can use a BST! Yes you can, but I'd rather use a linked list because I don't want to implement a BST for you... Plus you have to deal with the balancing to make it fully efficient. What was funny was that the other interviewer was like really?! And then they had a discussion about it while I'm just sitting there...
Also they didn't respond to any of their candidates.
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
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.
