I'm a student attending university. I currently live in city X and my family and I have been planning on moving to city Y for 2 years, but it always gets postponed for one reason or another. It's been postponed multiple times and me moving depends on my family finalizing it. My parents said it is basically finalized that we're moving in 1 month and a half. Note that last few times my parents said that it's "finalized", it never happened.
With that said, I need money to pay off tuition, car, food, housing etc. I applied to jobs (local restaurants, clothing stores and even part-time computer jobs because I'm a programmer). I got an interview with an IT company (not possible for me to work from home). During the interview, they asked how long I plan to keep the job. My response was "I don't know, until I feel that I no longer need the position" (I know, horrible response but it was like my 4th ever interview and I'm still getting the hang of it). They followed it up by saying "just keep in mind that it is a part-time job and there may be weeks where you work very few hours so you shouldn't expect to be promoted to full-time and shouldn't expect a raise in salary".
I agreed. They also asked if I was okay with working while taking university courses (they assumed that I'll be here in September taking courses when university starts).
They called me back for a 2nd interview. At this point I think my chances of getting the job are pretty high. But I also think that if I tell them "although I'm not sure how long I plan on keeping the job, there is a possibility that I may quit 4 weeks after getting the job", it will significantly hurt my chances of getting the job.
As a student, I need the money this job offers and gaining the experience will be good too, even if I can't use this employer as references.
With that said, in the 2nd interview, should I mention that there is a possibility that I may leave 4 weeks after getting the job even if it will significantly hurt my chances of getting the job?
