Had a very smooth process from linkedin sourcer to phone screen to recruiter to on-site interviews. The on-site process consisted of 3 paired programming sessions, architecture, and experience interviews. Overall, had a pleasant experience from the interviews. I received an offer after a few days, but declined because the offer was not competitive and under-leveled. I definitely should have asked for the pay bands and set my expectations earlier on. I would have not continued the process earlier had I known Square's leveling and offer would not be competitive. I think by law in California, it is now required to disclose pay bands although I did not try asking. Square is also more corporate feel than I expected, having some stingy parts that reminded me of Amazon: they have a pay by yourself coffee station, pay for lunch but then get reimbursed but you end up paying the tax, and other random things that don't exist at other tech companies. The diversity of some engineering teams need lots of work as well

Inital take home, followed by extension interview, followed by a coding challenge, followed by system design interview. The whole process took 3 months! The interviewers are usually really nice and want you to do your best.
