Debating between a few fabrics/patterns for a new suit, are any of these "too much" for a job interview?

Hey MFA,

I'm a computer science major in college and have started looking for a general purpose suit (formal events/job interviews/looking like a boss/ect.) While through personal taste I've decided that I want a nice grey suit I'm still a bit iffy on the fabric/pattern. Here's the three I have in mind:

1. Classic 100% Wool

2. Sharkskin

3. Prince of Wales

Would any of these seem inappropriate in the chance that I would need to wear it for an interview. From what I understand the computer science industry isn't very conservative so the probability that an employer would ask for a full suit for an interview is pretty low, but I want to have my bases covered.

Thanks!
