Code screen project review

Dec. 4, 2019

Introduction

It is such great project to work on. I had to prepare online code screen hosted on hackerrank.com. I pushed myself to practice two mock interview on leetcode.com, and also wrote a post for each algorithm. The preparation was so different, since I could not believe my eye to read those performance.

Preparation

I had to push myself work hard. Last week I spent time to watch videos from youtube.com related to personal finance research. I took risk and did not study at all until I spent time to work on code screen Sunday afternoon. I spent time to relax Sunday, played tennis, and then worked on code screen.

I did work on two mock interview on Leetcode for code screen, surprisingly two times I solved all algorithms. I wrote six posts to share my practice with my performance of mock interview. I just could not believe that what is happening, this is the real performance, am I memorizing those algorithms?

Here are those algorithms I practice. I will show the link here.

Code screen

I learned from the phone screen. My understanding of problem was not so good, I came cross the bug since I did not notice that there is a uniqueness requirement in the problem statement. I also spent 5 minutes to simplify my logic to write if statement. I spent 55 minutes to take the test.

Next day I was notified that I passed the online code screen. I got a phone screen.
