Ho presentato la mia candidatura online. Ho sostenuto un colloquio presso Two Sigma nel mese di apr 2022
Colloquio
Applied online, received an invite to a 75 minute HackerRank online assessment with 2 questions. Then a very general HR phone screen. Then a CodePair on HackerRank with an engineer. Their application management system has some issues. I was receiving emails to an old email sometimes and other times to my current email. I informed them of this and in the end they still sent emails to the wrong one. When on the phone, they use some sort of headset and/or software and the sound quality is not good. It's definitely worse than a normal phone call.
Domande di colloquio [1]
Domanda 1
Online assessment: perform a given distribution algorithm on tabular numerical data. Find the "best" subtree (this question uses misleading terminology of flows and cuts, but it has nothing to do with flow networks nor max-flow min-cut).
Codepair: explain hashmap, process and thread, and a question that is essentially random sampling without replacement.
first interview was 60 minutes long with a leetcode hard question. second interview was 2 back to back 60 minute leetcode hard with emphasis on data structures. each interview had a 5 minute introduction and 10 minute at the end to ask questions

Colloquio
Standard medium difficulty hackerrank. The question involved decoded an encoded string. It was not something I had seen on LeetCode before and I think was unique to the company. The question was not that difficult but I ran out of time right before I could finish answering.
