What people at iCIMS say
Reviews originally posted on Glassdoor.
Up to date tech stack. Decent amount of free food and drinks. The company has often shown their appreciation for the employees. Haven't experienced micromanaging. We're given freedom/flexibility to work however works best for us.
There have been many opportunities for me to further my career in my time at iCIMS
Culture and community building is excellent. People are always willing to help in order to solve a problem.
Very supportive colleagues, good manager and overall a transparent company with management that truly cares.
Fridays stuff-your-face-with-bagels. This is probably not going to be there anymore even after COVID-19 passes. Good coworkers depending on your team.
