This was a phone interview. There was only two questions. The first one was find numbers in an array. The second one was check symmetric tree. Both of the two questions were not very hard, but I struggled a lot. Luckily, finally I was done. Then interviewer asked me if you had any questions? I let him to introduce what kind of technology had been used in tripadvisor.

Good, although, sometimes struggling in providing you information about when interview will be leaving you wondering. Technical interview was good, I went into in uncertain as I wasn't sure about if I could solve a challenge. Recruiter was very nice and informative as well. Gutted to not progress onto next stages but they layout whole process for you and provide with you with feedback even if you fail the technical interview. I hope to re-apply soon when I become more confident with approaching technical assessments cause these do not correlate with your day to day duties as SE.
