The worst experience interviewing possible. First get an email from the recruiter, probably automated that I would receive the coding challenge which uses Lytmus.
After 2 days, finally get an email with the link to the challenge. Cool, I start the challenge everything goes smoothly and takes roughly 2 hours and 30 minutes to complete everything. Email the recruiter to follow up and they tell me that I had received an incorrect link and would have to retake the challenge. Why?! How hard is it to make sure to send a correct link, or to accept my submission. I am not your unpaid slave who has 3 hours every day with work and school to do projects for a CHANCE at working at your company.
Decided not finish the other challenge as my time is more valuable than that and don't want to work at a place that treats interested candidates like this. Not to mention their new challenge asks you visual recognition and API usage questions/challenges all to be completed under 2 hours for the CHANCE at an internship.

Question 1
Hashing-type question with emphasis on time and space complexities
Overall experience was neutral. Got an online assessment, finished it the next day. Did not hear back from them for 3 months. All of the test cases passed for the OA.
