30 minute phone screening with recruiter 1 hour interview w/ eng manager discussing past experience and skills 1 hour coding assessment with an engineer via CodeSignal, starting with a LeetCode easy and then adding slightly more complex requirements to the problem step by step. Ultimately was still a pretty easy coding challenge Finally, they invited me to do 4 HOURS of panel interviews across two days including sections on pair programming with an engineer on a coding problem, data infrastructure questions, and a "Q&A" presentation about a past project I worked on. Spent a week studying and preparing for this only for them to email me the morning of the interview to say that they filled the position already and were cancelling the whole thing. Utter waste of time and effort, do not bother with a company that treats its candidates with such blatant disregard
