Ageism is OK at CoStar! Started with phone interview then flew me to DC for 6hr onsite. Higher level morning session, lunch at Thai Restaurant with team, dive into SQL and C# syntax in afternoon. Didn't get any feedback onsite but 3 days later got bot generated rejection email. Later recruiter sent email indicating hiring manager was concerned I would not be "the best long term fit". Long term sounds very ageist - I'm 55 so I guess that means they wanted someone younger. Unfortunately I can't make myself younger and this type of ageist discrimination is very common. DC hotel they put me in tried to charge me for room instead of CoStar and CoStar has still not reimbursed me for incidental expenses incurred during interview (food, metro, parking) and they won't reply to phone call or email. Shame on CoStar.
