Behavioral Technical
You typically apply online via Fastenal’s website, which will prompt you for your email to forward a unique application link. From there, HR at their main office goes over your information to check if your skills align—this can take up to a couple weeks. If they do like your profile, you’ll get an invite for a quick phone chat—usually only about 5 minutes—and you can ring them during business hours (Monday–Friday, 8 AM–5 PM CST).

Technical Coding
The interview experience was good overall. My technical skills in .NET and Angular were assessed and deemed strong. However, I was ultimately rejected because I am not currently using Angular in my project, which I found perplexing as this seems like a detail that could have been identified during the initial screening. I felt I answered the Angular questions well, and all my .NET and SQL questions were answered effectively.

- Can you rank your SQL proficiency?
- There was an easy coding question.
