Called by recruiter who was super judgmental starting out, said I had to “research TCP/IP and C++ since I don’t have that much experience” so why even call?? Interview with two old guys that started with an insult and never asked any technical questions. They said they wanted to revolutionize phone technology, whatever that means. Tried to maintain a respectful and positive attitude even then, but they didn’t have anything to offer and didn’t talk about the benefits of working there, had to ask about it. Denied a day later. Honestly didn’t even want to do the interview after that recruiter.
