Yelp Front-End Engineer interview questions

Applied for position in February and reached out to recruiter on LinkedIn. Exchanged a few emails and after a phone screen, the recruiter set up a coding challenge. Communication wasn't the best, and I had to reschedule once due to the interviewer not being available. I was informed that it would be a timed challenge and that it would include front end technologies. I assumed there would be some javascript involved, but the challenge was strictly HTML and css. Very easy! I passed the challenge and set up an interview for a Skype meeting with an engineer. I was not given any information on this interview, and was caught off guard by one question he asked me. The answer he was looking for involved an outdated jQuery method, and I answered using AngularJS. So, I think that led to his dismissal of me as a candidate. Overall it seemed like he wasn't too thrilled about yelp or interviewing me. I would assume the already had other candidates in mind. Overall, I was not properly prepared for either interview. Both were very easy, but they were very transparent about having their eye on another candidate.

I applied online and got an email about a week later asking for a phone screen in the next week. Everyone else is right on the money about how it goes: Questions about your background, why Yelp, do you use Yelp, etc. Then they get to the technical questions. Important! If you're applying for a front-end job, read this and not all the other interview reviews. I got seriously scared that they were gonna ask me about octets and really CS-based questions that I never use in my day to day work. I'm self-taught so a lot of stuff that people learn in classes never got to me or I glossed over it. Anyway, the questions are below (that I remember): 1. In HTML, what does <title> do? 2. In CSS, what are the different values in the Position property? 3. How would you hide images on a page? 4. Would not naming a variable in JavaScript cause an error message? I passed and got send a coding test. If I pass that there is a Skype interview and then an in-office interview.
