I plan on wearing a suit but I am wondering if I can go a little casual and skip the tie.
Quite simply YES You should always dress smartly, whatever the work environment Catherine
if you wear the suit, wear a tie
No dude, it is better to over-dress for an interview. Going in tie-less will project a cavalier attitude. Image is an important part of sales.
For a first interview wear the suit and tie. If you end up being overdressed it will be seen as a sign of respect if you go casual and end up being underdressed it will be seen as a sign of disrespect.
If you have one, go for it. It could only work out to your advantage.
