So about 9 months ago I finished an internship at a company. I went for an interview where there were 10 positions going. I wanted the job very much but absolutely fell apart in the interview. I was so nervous I was sweating, shaking, mumbling. I cannot even imagine how I came across. Somehow I managed to give some good answers but overall I must have come across as very incompetent! My mouth was so dry I had to keep coughing!
I cringe now just thinking about it.
The manager was clearly unimpressed and started laughing at my answers. After my interview that was only 20 mins long I decided to use it as character building and move on.
So 9 months later I re-interviewed when one position out of the 10 came up and I nailed the interview. I have since excelled in the role and I'm back to my extrovert, confident self. I've remained in the role now for several months and have had excellent appraisals.
So I'm happy.
Only one issue. The manager that interviewed me is very odd. She sometimes has to come into our building and she's like the devil wears Prada boss! She's standoffish and a bit cold but has her moments of humour. She's not a bad person.
But when she seems me she is very shy. Doesn't make eye contact and will just stare me the whole time I'm in the same room as her. She does it subtly but I can see her in the window reflection or mirror...just staring. It's like she's analysing me! She acres her eyes up and almost glares, lips pursed. It's so intimidating!
Someone called my name from the corridor and when I turned round she was practically breaking her back trying to see me. She's a heterosexual married woman so doesn't have any kind of romantic crush! 
If I need to speak to her on the phone she always says she's unavailable and once when I needed to speak to her she said she wasn't available and when another member of staff called her she started the conversation with (someone called xxx called and said they needed to speak to
me). She was unaware she was on speaker. My manager then pretended she needed me for something to get me out of the room.
Maybe she just found the interview cringeworthy and doesn't want to be around me as it's awkward but she's been a manager for 30 years she must have interviewed thousands and I know two other people she has interviewed and she's find with them and they weren't successful.
I just don't know what the issue is. Nothing I can really do but AIBU to find it a little disconcerting?
