I applied online, and within one week I had a phone interview with the recruiter. Subsequently, I was asked to develop a web crawler in my preference of language. As I was searching for a job, I wanted to make it perfect. I spent around five days to develop the application, and the application was flawless.

During the next online interview, there was a discussion over my code. The interview went pretty well. The next day I got an email stating that my experience and their requirement didn't match. This baffled me literally. Couldn't they do a better job at filtering resumes at the first hand itself before giving an assignment? I assure you my resume was written in English only, and I have a very nicely structured CV.

If my experience didn't match the job requirement, then why can't you reject my candidacy on the first hand instead of wasting my time? I totally acknowledge the right of a firm to have its whatever standard of hiring. However, there is a difference between being selective and being a time-waster. Please stop wasting candidate time.

Design a web crawler in whatever language you want. One answer.
