HR person was professional and nice to talk, however managers feedback took too long with no deadline and I found another job in the meantime. After that I stop looking for a job so I don't know if they would really pick me.

Not a serious company, they schedule an interview with you and then tell you to wait for a feedback which never comes, I also contacted their HR via email because I found another interesting position at the company and wanted to apply and never got an answer, I do not recommend Global Blue and will never apply again
