Majority of the companies don't respond back.

Till now I have been able to give maybe 5-6 interviews out of which 2 people responded back with feedback .

One company just sent back a generic email about how I was not looking for but the second company/startup did give a nice and detailed feedback.

And it just seems like there are more frontend related jobs than backend. I primarily do backend.

I have been applying through stack-overflow, RemoteOk and Hacker-news who's hiring, however I haven't really applied using Angel-list till now.

I'll check out Angel List
