Pros
Location of the HQ (Chicago), nice looking office, benefits were great. (Glassdoor asked me to complete at least 20 words for this section, there's very few nice things that can be said for Clayco..)
Cons
I have very bad experience with this company. I could only stay less than a year. People do backbiting, failure is an opportunity to be used against a person, no value to people but the company. I have been told many times "Go figure out yourself". The worst part is Clayco is always under-staffed. You are expected to work at least 10 hours to get things done yourself. Management is living in a different world where they only oversee the budget and billings of a project, no team spirit, no value to people. I am so glad that I left there, this company should be your last bet if you don't have any other offers on the table.
