      Senior Software Engineer Interview

      Average interview

      Application

      I applied through other source. I interviewed at Apollo.io in Apr 2021

      Interview

      Was directly invited by their CEO, Tim Zheng, and the process went smoothly at first. 1. Took the React Tic-tac-Toe exam - finished and feedback from them is that I did well. 2. HR Interview - nothing specific 3. Live Coding interview - Combination of Stack & Queue data structure problem 4. React Take Home exam - re-implement 1 page from their application During the HR interview, I told them that I won't take the take-home exam unless they have enough budget for my expected salary. Initially, I told them I would submit not later than a week ho the HR said to finish the take-home project as soon as possible since it would be a big factor. So I finished the entire thing in 13-15 hours. The project + CICD Setup with Heroku Deployment (since these were indicated as bonus points). A week and a half have already passed and I've followed up with them for the result but I received no reply. They couldn't have the decency to respond to inquiries and follow-ups but they have the audacity to rush me in doing the take-home project.

      Interview questions [1]

      Question 1

      You have two strings. Both strings are series of numbers. Implement a function to check whether the second string is a valid pop sequence of the first string. Ex. "12345" "32145" "12345" "54321" "12345" "21543"
