Interviewed with a Developer. I had to solve 3 coding problems. I applied for C# engineer position, whereas I was asked to code in Javascript. I wasn't expecting that. The interviewer expected me to know Javascript. I didn't get an offer due to lack of Javascript knowledge.

Scheduled for one hour but ended up going for two hours due to small talk after completion of the technical portion. Technical interview was in JavaScript. Was able to perform all tasks in interview. Received e-mail a week later saying I had all the qualifications but I wouldn't be receiving an offer.
