RetailMeNot Senior Software Engineer interview questions

A standard interview process which begins with the call by HR and an online coding test and then the technical round. I completed the online coding round and then attended the technical round. The interviewer in the technical round was the most unprofessional one I have seen in my career. He just copy-pasted a question and said solve. No introduction, no collaborative approach and the guy was like a statue without even saying anything. I think this is one of those coders as robots culture. Never expected such strange engineering culture in a product company. Won't recommend spending time interviewing with them. Anyway, I couldn't solve it and the interviewer was like a statue even to questions as it looks like they expect people to mug up and code and type it like a robot. Got the rejection mail the next day itself. That part at least is good from the HR process standpoint view as many companies these days don't even show the basic decency to inform candidates about interview results.
