For a bit of context, I had two interviews recently one with a hearing aid company and one with a roofing company (both corporate roles). I thought the hearing aid company interview went well and the hiring manager thoroughly detailed the next steps of the hiring process. She asked for my age during the interview as well and I responded that she wasn't allowed to ask for my age and upon me saying that she profusely apologized. So all in all I thought I was at least getting a second interview - 15 mins later she emailed me saying they weren't moving forward with my application. The Second interview with the roofing company didn't go badly per say but the vibes were mildly off. They asked if I had specific software experience that was MANDATORY for the job and I said no but I am willing to learn. Also, In my questions for the interviewer I asked if they had any hesitancy in hiring me and they also said no. However, when I asked what the next steps are in the hiring process they said we're still interviewing other candidates. From what I've learned in this subreddit that answer is generally not a positive sign. Anyways, I sent a thank you letter. Next day I was offered the job and the recruiter kept saying how much they loved the thank you letter. TLDR; this is more of a vent for me as I tweak and I obsess over every minute detail and signs of body language when it comes to interviews. At times looking for a new jobs can be bleak but just don't let it consume you like it does for me. Don't google signs an interview went good/bad as you'll only continue to spiral (at least for me). Just know if you have completed the interview, everything after that is completely out of your control.
