I had a similar experience. Started with the video interview they asked for after seeing me resume bombed it I had 2 minutes to answer complex questions and let’s just say we had about 30 seconds of actual words. But I got a call for an in person interview and the nerves got me on that one and I thought it was a disaster but I got the job even with the fact that it’s a customer facing field service role. It’s been 18months and there’s good and bad days but I have a good boss and great company and nobody gives me a hard time about it. So don’t let shitty interviews discourage you the company’s that do quietly let it influence them you don’t want to work there.
