I sent a cover letter to a company that is far away from where I live. A few days ago, I got an email from them to come to their office for an interview. After considering my circumstances in last few days, I don't think it is possible to travel to the place where the company is located. The first thing I think of is the cost. Even if I come all the way to the city where the company is located, it is still not sure that I will be accepted at the company, even though I would have spent a lot of money for a plane ticket.
I am a bit uncomfortable asking them to interview me via Skype (it seems like I am dictating their interview process). Is it fine if I say: "Where permitted, I would be glad if we could interview via Skype?"? Will it undermine the employer's first impression of me?
