Wayfair Senior Software Engineer interview questions

I have never met with such a rude and arogant employee or interviewer in my life. The problem he asked was adding of two large no’s in Java. I told him the approach and moved with writing the code but during that whole time he was passing rude comments and laughing as if I have done a blunder. I will not recommend anyone to go for interviews with this company. He was not only rude but had an intention of insulting the interviewee. I genuinely feel that nobody has the right to insult the interviewee by passing comments like “are you giving interviews for first time” or “we are doing such additions since class 1” and laughing in between. Even if anyone dont know what what no’s are still no one gave the right to insult. Pathetic experience, worst interview. No words for interviewer.

Spoke to the recruiter on an introductory call. She only sounded happy when informing me that she was going on a vacation the following week and how "I'm so busy this week". She then wouldn't tell me the name of the hiring manager, when I asked so that I could look into their background to determine if I was interested in working for that person. She glossed over the actual job responsibilities and focused more on questioning how I'd impacted revenue for the product I currently work on. This tells me everything I need to know. I won't be continuing the process based on this experience.
