The interview process made me very hesitant about joining the company because it was so strange and not well thought out. I had 7 rounds of interviews total for a mid-lvl engineer. 1st technical screen was a 1hr coding interview. I was 90% done with the last problem when then the interviewer stopped me due to 5 mins being left. They then erased my work to fill in the answer themselves. Despite the interviewer having 10 YoE in SW and knowing the answer, they struggled and took 20 mins to get a working program. I then got feedback after the first round saying I passed, but the interviewer ironically said that I struggled on the final question. Clearly they had a hurt ego, but I got past the round so no harm, no fowl. Next was the actual core interviews. At this point they make you sign an NDA and let me know I had 6 more rounds. During these interviews, I was really confused as to what Square was trying to achieve or learn about candidates. No one asked me a single behavioral question, qualifications, or even basic programming theory. Instead, it was hours of theory questions, a couple more coding questions (which was basically a repeat of the tech screen), and maybe 2 questions about my resume. Some of the theory questions were really dated too. Interviewers did seem a bit inexperienced since they didn't know much about other facets of the topics they were interviewing about. It seems like the only reason they make you sign the NDA is so other people don't find out how much of a mess the interview process is. It's true Square is taking in surveys to improve the interview process and Everyone talks about Square having "growing pains", but you have to remember that they've been around and interviewing for over 10 years. It really doesn't get much better than this.

2 30 minute calls with team lead Followed by invite to interview on site but couldn't go so I did 4 consecutive technical webcam interviews Was recommended to another team and did one more technical interview with team lead of another group.
