I was referred via an old co-worker and the hiring manager reached out via LinkedIn and gave me an informal interview. The interview went well and he told me he would move me to the next round, but then I never heard from him or the recruiting team. I had to ask my old co-worker who told me they were waiting for other candidates to move forward and then if they weren't a good fit I'd move forward. This contradicted what the hiring manager told me in the intereview

It was structured and fast, and I know i aced the lab but it turned out as i failed which was hilarious and they didnt tell why I failed the test when the simulation mechanism showed the expected results everytime you complete the respective individual parts of the test.
