I have a full-time job as a software developer that is enough to support me, but I am looking to find a temp job to help pay off student loans quicker, among some other expenses. I interviewed with a company that I found (on Craigslist) that would have me doing some simple work that I feel I could easily accomplish, for a few extra hours each week. However, I wasn't sure how I felt about the development process or technologies they use, and didn't have too good of a feeling for one of the interviewers, although I may not interact with this person much. The job is remote and I could work at a decent rate after my primary job.
My question is: if I find that this temp job is not a good fit for my time, are there any repercussions that might come from trying the job for a couple of weeks or months, and then leaving? I won't need to put this job on my resume, and I will still be working my primary job so there will be no employment history gaps, but will something like this show in a background check for future jobs, and be a bad mark against me? I'd like to have this as a casual part-time job that I can leave at anytime, even within a few weeks, just to provide myself with a bit of extra money to help reduce my loans. But I don't want to risk hurting any future opportunities in my career.
So is it alright to accept a part-time job with the intent that I can leave right away at any time if I want to? Or is that a poor attitude to have going into a job, that may impact my future career in a background check or otherwise? Thanks for any help, it would be great to have advice before I decide to take the position.
