At the time I was a firmly entrenched back-end dev and was put onto this job by a recruiter and it was just up the road from the house, blissful commute through a park, not the best salary offer but that was negotiable, in short - great potential. In the nitty gritty of the interview I found they asked me a lot of javascript questions (okay I thought, maybe they were testing my limits - they were confident in my 'advertised' back end skillset from just reading my CV?). Turns out the recruiter had put me up for the wrong position, it was front-end and to my credit they were willing to hire me as front-end but I had other interviews for positions I'd prefer.
