I was recently hired for a seasonal part-time position where I had jumped the gun after discussing my studies by telling the interviewer (who is manager A) that I will be graduating in a few months and that I am obligated by my program to get a job within a few months of my graduation. I did this because I am honest, which I suppose is a good quality, but I was warned that if they hired me (which they did) that I might not stay after the season if they can't guarantee I will be staying long enough to justify hiring me for a non-seasonal position.

I am now up for an interview at this same company that I am working for seasonally in a position that is a major promotion from the seasonal part-time work I'm doing at the moment. The manager of that group (manager B) seems to like me and I had several good casual chats about my skills after one of my interviews and while on the job in this seasonal position. But it is no surprise that manager A told manager B about my potentially short-term stay. I tried to show commitment by explaining that I am specifically looking for work to stay in this area if I can (it is significantly harder to get a job in my field in the small area I live in right now, which is why moving is a real possibility). Taking up my parents' offer to stay for a year or two while saving some money seems like a reasonable financial decision at the least.

I have an interview with manager B this week and I'm pretty sure this question (Will you be leaving in 6 months?) is going to come up in the interview, so I would like some help navigating it.

My initial thought is to stick with the honesty since I can't take it back. That, yes, I can guarantee them that I will be working with them for at least 6 months if not up to 1 year or more. That I am also interested in going to corporate for the actual career I am looking into (which is, at least, not a loss for the company as a whole, even if just the branch). They need someone immediately, so I can at least give them that reassurance that they will know when to look for new candidates rather than scrambling for candidates if I were to leave unexpectedly (like the person whose job just opened up).

Any thoughts would be greatly appreciated.

P.S. The company I am at right now is in the same domain as my intended career because I wanted to stay consistent. But the part-time work I'm doing is significantly lower rank than what I am qualified for and intend to do in my career. We're talking a difference between a $30k salary and a $100k salary. But I need something to pay the bills while I finish my studies before I take my first "real" job.
