Newtopia Senior Full Stack Developer interview questions

I went through a meeting with the CTO, then did an incredibly long take home assignment (about 10 hours of work), then a 1.5 hour interview with several people at the company, then I was supposed to meet with them for an offer. After all of this they cancelled on me twice to go meet to discuss an offer. I later find out it was because they were being dishonest and didn't disclose they were interviewing other candidates and that I wasn't the top choice. The least courtesy they could have provided would have been to inform a candidate who put a lot of effort into interviewing that they are not the top choice. Candidates are people. Respect them.
