Hi, I'm in the interview process at amazon. I'm applying for a front end developer position.
To this point I've done:

1. An online assesment
2. A phone interview that covered one coding question, some question about servers, general question about data structures and alittle bit of HTTP.

Now I receive a confirmation that thew want to move forward and keep going with the process. This time they told me that the interview is going to be a front end interview.
I don't know where to start or which kind of questions I should expect.

Also there is something curious. For the first phone interview, the recruiteer tolde me that it was going to be a business phone interview, but a few days before the interview, the coordinator of the interview told me that I need a comuter because it was going to be technical. In that interview I did not recieve any behavioral question.
And for this coming interview, the email says that the interview will cover my front end skills. And I'm kind of wondering if there was a mistake or a confusion about the order of the interviews.

Thanks in advace
