Initially, I did have a good and relatively normal interview process. There was a screening and a group technical assessment with two people. I passed all interviews and they said they were pretty sure I was going to get an offer, but they needed to hire a senior engineer first. I said sure, and followed up regularly. Well, a year or so passed, and they had me do an onsite interview in Montgomery, TX, basically in the middle of nowhere. I did the SAME technical interview (as in, pretty much the same questions asked and the assessment) that I did the year prior, and they told me I failed. Also, their senior software developer onsite there was very snarky and I could already tell it wasn't a great place to work due to his attitude. I asked for feedback from the interview since we had all invested a significant amount of time in the interview process, but they ghosted me afterward.
The funny thing is I was going to turn down the job anyway because of the very long distance drive, in-office requirement, low pay, and poor attitude of the team's onsite lead. I'm not sure how they're going to hire anybody that would stay there, but it's also not my problem. Terrible interview experience!
