Interview
The interview process took quite a while because there were several rounds and planning them around my schedule took a little while. There were 5 total interviews -- the first 4 of which were phone interviews and the last one a Google Hangouts interview. All of the interviewers except for one were very friendly and helpful. To prepare for the interviews, I would recommend focusing on CTCI and doing Leetcode Medium/Hard problems.
Interview questions [1]
Question 1
Typical data structures and algorithms questions. The majority of my interviews focused on graphs, arrays, and hashmaps. It should go without saying, but know space and time complexity of the solutions you are implementing.
