I completed an internship in the past month as a Senior Consultant for a client, and I'm currently interviewing for a summer internship at a startup. They asked me some questions about my previous experience, and who the client was and if they have a website that they can check out.
I was just messaged by my previous client saying that the interviewer have contacted them asking for a reference! I was really taken aback by this, because I didn't give any permission for this, nor did I indicate that they were a reference that could be contacted. The startup is based in Germany, do they have a different culture regarding this or something?
Is this a red flag?
