Square Software Engineer interview questions

1 Technical screen followed by an onsite consisting of 2 pair programming technical sessions, 1 system design question, 1 past technical design question, and talking to the hiring manager. The onsite process was fine and the interviewers were nice to talk to. Questions were fairly standard and not too difficult either. They also give you the system design question before the onsite so you have time to prepare. But the process after the onsite is completely backwards. I passed the onsite but there was a second round of talking to hiring managers for different teams after the onsite, and then even after I talked to a hiring manger, they asked me to talk to the tech lead for the team as another test. They keep stringing you along after you've already put so much of your time and energy into the onsite, only for them to drop you at the very end. The entire process took SEVEN weeks.
