The interview process started off well, eventually turning into an unexpectedly lengthy 5 round loop for a support role. Even though that level of interviewing felt excessive for the position, I took it and embraced the challenge. Unfortunately, I didn't make the final cut, and I was never provided with the specific reasons why. Looking back, I realize I should have asked for detailed feedback to understand their decision, but at the time, I didn't bother pressing the issue and decided to just let it go.

Was sent to the wrong building by HR and sat around in the lunch room for an hour waiting to be called into the interview. Either its incompetence or just lack of caring. Learned later hired an internal. Thanks for wasting my time.
