I applied through university. The process took 2 weeks. I interviewed at Datadog (Toronto, ON) in Oct 2017
Interview
Worst interview ever. It seems to me that there was a huge focus on getting running code to work. My interviewer kept asking me to run the code rather than focusing on the thought process.
Easy questions, they asked in-depth questions about a project that I had to verbally present. Then, they asked 3 leetcode style questions, around leetcode easy to medium. They asked me to explain the time complexity of my solutions, and they were very kind when I made mistakes
