I applied online and was contacted next day by HR for a screener. Screener went really well and I had a Hiring Manager interview the next week. I thought the hiring manager interview went well but it's now 2 weeks later and I haven't heard a word, despite follow-up on my end. Pretty disappointed that such an innovative company cannot bother to keep candidates apprised of the interview process/I wouldn't have expected interview ghosting from Square.

MANY interviews; phone, web, 2 in person interviews on 2 different dates. Dress nice but casual but not sloppy as casual attire is the daily norm. Do NOT wear a suit or tie since it would most likely be viewed as not a "good fit" with the culture. Smile and be friendly!
