Over a year ago I applied for a position with Company A. I had an interview with them, but recieved a job offer from a different company shortly after it. I informed Company A that I was no longer pursuing job opportunities. Recently, my situation changed and I contacted Company A again. They basically told me to fill out paper work before I can do the next level of interview, but then they gave me a job offer and more paper work to fill out.
Initially I replied to the email saying I would take the job offer, but at the last minute changed my mind (for several reasons). By e-mail I told them I decided not to accept the offer but I also mentioned that the paper work (in particular the contract they wanted me to sign) seemed strange.
Today I got a voice mail and emails asking me to contact them so they could explain everything to me. The HR rep said she contacted my boss and they really want me on board.
I'm towards the beginning of my career, so tell me if I'm looking at this wrong, but something doesn't add up. This job pays close to minimum wage and is part time. Why would they bother to still be contacting me? (A small part of me feels that if they changed the contract I may still be interested, but I think at this point starting a job with this negativity wouldn't be good) Could this be some sort of scam? The company isn't huge but is well established (existed since mid 2000s). Should I bother to reply to the email, and if so what should I say? The HR department is in another country and I don't want to spend money on the long distance phone calls, should I tell them this?
