This question already has an answer here:
TL;DR I agreed to a job interview and now I don't want to go; how do I explain it to the HR without burning the bridge for further applications to the same company?
Some time ago I applied for multiple job positions, as I perform very well in my current company and wanted to get some perspective on how much raise I can ask for while being periodically evaluated.
HR from one company called, we agreed on the interview date, it's next Monday. I received an invitation email and then realized that the office I would work at is 1-hour drive from my place of living, and I definitely don't want to travel 2 hours a day (on good traffic days) to and from work. I do know it's my bad that I did not consider it before applying and agreeing to meet.
However, I like the company culture and projects very much and I think I might apply there again in the future, preceding it with the relocation (I rent a flat, it's not THAT big of a deal, just definitely not now, as I relocated recently and like it so far).
Difference between my question and possible duplicate is that I (in my opinion) don't have an honest excuse to cancel the interview, while OP in the other question does - he decided to stick with his current company.
Another difference is that it leads to the great answer by ItWasLikeThatWhenIGotHere.
