Thumbtack Front End Engineer interview questions

The recruiter sent me email on Linkedin.com. I had an phone screen with the recruter, and he sent me a link of a code challenge. I submitted the code, and got a feedback from the dev team and basically told me I am not a good fit. Most of the feedback are fair and objective; however, one of them just got my nerve. The exact wording is "HTML is a DIV wonderland". Maybe I am too sensitive but I do feel some laughter when the guy/gal wrote that comment. Also, if you really desperate to get a job from Thumbtack, you better spend 4 to 6 hours to get your code perfectly written because they will pick on every detail from your code. And remember even though you spend 3, 4, or 6 hours on the code challenge, it doesn't mean that they will give you a ticket for another phone or onsite interview. So if you don't want to accept the fact that you might waste 4 or 6 hours on writing the code without getting an onsite interview, forget about this position. Go spend the time on hunting another one. BTW, I feel that the recruiter could be more responsive on replying email. In some instances, I never got a confirmation email or reply from him. Hey, in conclusion, the company is not a good fit for me!
