      Average interview

      Application

      I applied through a recruiter. The process took 1 week. I interviewed at Hola in Jun 2018

      Interview

      The interview is divided into 3 steps: 1) general question with internal recruiter + offline coding test on gDocs 2) live coding test with an Engineer 3) live coding test with another Engineer There are no technical questions, the coding tests are quite interesting and challenging. Focus on code optimization, classes, and asynchronous functions. Check their DNA page to understand why this interview process is structured in this way.
