Frontgate interview questions

Went through a terribly long interview experience- 5 interviews with 5 different people. Same questions over and over again. I thought I hit it off well with every single interviewer and fit the role really well (was also told this by multiple interviewers). Three weeks of my life interviewing for a company that was never going to even follow up with me afterwards. I followed up three times just to be told after a month of waiting that they decided not to move forward with the role. The most disrespectful and careless company. I'll never shop with them again, let alone apply to any sort of position.
