About 18 months ago I was looking to change the sector I worked in. It was an unusual swap (although not unheard of) and required quite a bit of extra prep/work/revision in my spare time, plus jobs don't come up very often in the new sector so lots of scouring job websites/ meeting with recruiters etc. I was very keen to get one of the few jobs on offer and did lots of preparation for each interview.
Company A invited me for an interview and then a second and a third interview. I felt they had gone well and really liked the sound of the role and the vibe I got in the offices but after the third interview I never heard from them again. I even emailed after a few weeks to ask for an update but heard nothing at all. I was disappointed as I'd put in a lot of effort, taken time off work for interviews etc and I doubt they'd interviewed more than 3 of us, so wouldn't have been a huge effort to just send an email saying "sorry, we've given the job to someone else". Instead they left me in limbo and it felt quite disrespectful as they'd seen me three times over a period of 6 weeks so I wasn't a complete random.
In the meantime Company B invited me for interview and second interview and offered me a job, which I took. I have now been at new firm for a year and, whilst it's not perfect, I really like my colleagues, get good work and am happy for the time being.
Anyway, this morning I have had an email from Company A saying they are looking to hire someone again (in the department I interviewed for last time) and they think looking at my LinkedIn profile I would be perfect for the job. In a way I am flattered as it's very rare to get a direct approach from this type of company (they normally just advertise/ use recruiters) but also in a way I want to reply and say "absolutely no chance after how you treated me last time!"
I don't want to move anyway as I'm happy where I am but you never know what the future holds and I could well eventually want to move to Company A at some point further down the line, so I don't want to burn any bridges.
However, WIBU to point them to their past behaviour as a reason for turning them down now? Or would that just be cutting off my nose to spite my face? Any advice gratefully received!
