I recently got my first job and I have accepted the offer. Another employer who had previously put my application on hold wants to interview me now. How can I politely turn down the call for interview? I had genuine interest in working for the company but somehow things didn't work out earlier but now I am already taken.
Just tell them the truth — this is a very common occurrence and people drop out all through the process due to other offers.
In person or over the phone, just say something like, “I really appreciate the offer to come in to interview, but I’ve just accepted another role and I don’t wish to waste your time. I’d love for you to keep in touch in future, though.”
They’ll rarely actually do this (i.e., proactively get in touch), but that’s just politeness and a way to keep the door open.
Smarten it up a little for an e-mail or letter and you’ll be fine.
In exceptionally rare cases, you may get a little heat from a recruiter. Don’t worry for a millisecond about anything they say — in real life you have to do something particularly bad to get black listed from a company’s application process.
