Roadmunk Software Developer interview questions

I was referred by an employee and got the call from their HR within a day. I was then given a code review assignment and that's when came to know about their behavior. So the email containing the details didn't mention that I should not be removing the code even if thats not being used. Ideally if a code is not used, you shouldn't have it. That's what I suggested and they weren't happy. Secondly, no where in the assignment it was mentioned about test cases. So you do what you're asked for and I didn't do more than what was asked for. Again they weren't happy. They expected me to infer things on my own. It was just unfair. They didn't reply to my emails regarding this and I thought I should post a review online. I'm never applying there ever! Well, if you reject someone and give a valid reason for that, it's a constructive feedback. They gave a useless feedback. I think they're not doing very well now so are confused about hiring more people or the HR needs to show that they're doing something so they jump on interviewing just to show what tasks they did on their timesheet. A justification for not getting laid off and keep receiving their pay. Well, if it's working for them. Keep it up!
