StockX Software Engineer interview questions

First interview was a recruiter screen, then a Hiring Manager screen, then three more for system design / architecture, data structures, and a culture fit interview. Overall process took about 2-3 weeks from application to all interviews being done to hearing back

One of the most unprofessional experiences I've ever had. Every interviewer was late. One didn't even show up. Then when they did show up, my tech interviews went very well. I could answer every question and even got feedback that my preparation was excellent. Then after the four rounds, they tell me that my tech rounds didn't go well, which was just impossible. A huge waste of my time. Wouldn't recommend this.
