I applied online. The process took 2 weeks. I interviewed at Walleye Capital in Jul 2025
Interview
Got a HackerRank 120 mins 3 questions. First question was barely a leetcode easy. Second was an API question leetcode medium. Third was algorithm leetcode hard. Could not solve third question. Did not progress in the interview process.

Question 1
They asked me about API calls and need to make an algorithm's runtime low.
Multiple rounds - 1st round is a hard online assessment followed by technical interviews but the criteria for selection was not clear. I got rejected after the first round which was resume screening.

Question 1
They asked me about my internship (AI Intern) where they briefly asked me about my project work and the technologies I used. The interview chose to focus on my knowledge of database systems although my resume was clearly geared towards an AI/ML Engineer role. I was able to answer every question correctly.

Interview
An automatic online assessment sent out to everyone that is 180 minutes long, 4 questions, and expects you to know a wide range of topics including complex SQL, functional programming, API requests, and algorithms. Got all the questions correct except the SQL one. Very unpleasant experience and a tedious waste of time. The fact that they send this out to everyone without even reviewing their resumes shows they don't care about the time of their candidates. Haven't heard back but assuming I got rejected.
