Since I finished college I was on a interview loop. I'm so tired, at this point making my own company and freelancing seem more reasonable. I don't understand why there must be 4 different persons asking me the same questions just so in the final to give me a lower offer than we previously discussed or to ghost me. I had a bad opinion about HR when I was a student and didn't work based on how a few of my friends and family treated, now that I'm looking for work and have to deal with their bullshit daily I literally started to hate the people working on this dep and their lack of respect.
