There's a company I'd really like to work for that has 2 different positions open, one for a full-stack web developer, and one for a mobile developer. I had a really hard time deciding which one to apply for, and ended up applying to the mobile one.
I got far enough in the interview process that they've given me a mobile programming challenge to do, but I'm really regretting applying for the mobile position. I wish I had applied to the web one, because I'm much more experienced in web and like it better. I'm not even 100% sure why I decided on the mobile position in the first place. It seems silly to go through this entire process if I don't even feel excited about the position after all, but I'm still really excited about the other position.
Would it be a bad idea to send an email asking if they'd consider me for the web position instead? The company is small enough that I don't think they'd need to go through an entirely different department (during the phone interview they kept asking if I was applying for the web or mobile position), so I think it would be okay, I'm more worried that this would look unprofessional, and like I don't know my own ambitions and talents.
