Google Interview Performance Analysis

Nov 17, 2021 8 Comments

Completed onsite at google for L4 role and waiting for interviewer feedback to come in so obviously I’m finding plenty of time to be anxious and consider what I did wrong.

My evaluation is that I got: 2 strong hire, 1 no hire, 2 hire. What’s the thought on this being enough to make it to HC?

1. Behavioral- answered all questions wanted and at one point it was mentioned what I described goes beyond the requirements for L4 (my goal). I take that as very good and likely strong hire
2. Algo - 1 problem which was probably medium LC but had to be n! Complexity which made it a bit harder than average. Some things were not completed like string parsing for all cases a couple others. Definitely got the core of the problem correct though and explained well.
3. Algo - Solved from with optimal complexity but it honestly wasn’t how he described to do the problem as it required some geometric math and I had no idea what to do there so punted / tried to change the criteria to suit a more well known strategy. Hopefully that’s ok otherwise this problem totally went wrong. He seemed fine with it and did let me do it so I take that as ok but he did fall out that it’s not the way it’s defined.
4. Algo - Couldn’t figure out optimal O(n) solution but I knew there was one. Instead of blocking I asked to code with O(n^2) in hopes it helped me find optimal as I was totally stuck. Ended up making a n log n solution. I was disappointed and it was not super clear what I was doing to the interviewer. Worst performance
5. Algo- solved problem and all follow ups with several minutes to spare. LC medium type problem. Last follow up I could’ve mentioned a slightly better complexity solution but would’ve been rather obscure knowledge imo. Had a good conversation, best performance for sure.
