Background
At this point I had already taken the online assessment. In the online assessment I had 2 problems:

  1. Top K Frequent words (19/21 test cases passing)
  2. Reorder log files (22/23 test cases passing)

My recruiter followed up with me and said that they'd like to continue the process with another phone screen.

Interview Questions
LP / Behavioral [30min]

  1. Describe a time that you developed something with a unique and non-trivial approach
  2. Describe a time that you made something way easier for a user

There were also some followup drill down questions in here, but that was the gist

Coding [25min]

  1. Count number of islands (super common LC interview question)
    -described DFS and BFS approaches, tradeoffs between the 2 and went with BFS per interviewer. no big deal.
  2. First non repeating character in a string (another super common question)
    -I used a 2 map solution of counting frequencies and storing first indices. I think there may be a better solution to this but interviewer seemed to think it was fine

Asking Questions
This went for about 10-15 minutes. Interviewer didn't seem to mind going over and letting me keep asking questions.

Summary
Overall, I hope my behavioral / LP question answers went well enough because the coding aspect of it seemed really easy and straight-forward to work through. Will update in the future with results

Update: moving to on-site
