Full Experience

I interviewed for a senior fullstck position in Seattle

Recruiter Screen: Typical stuff. Make sure you have a good answer for "why do you want to work here"

Coding Round: Part 1) write a function to determine if a given string is a palindrome, you are allowed 1 deletion. https://leetcode.com/problems/valid-palindrome-ii/description/

Part 2) Given two sorted arrays, return a merged sorted array containing the sqaure of the elements. Negative numbers make this a bit tricky.

The interviewer literally just gave me the solution, which I did not appreciate. I wanted to solve the problem my own way but he wouldn't let me.

React Round: Build a website that has two tabs, each containing a list of items. Popultate both lists from a network request. Implement "follow/unfollow" for each item.

Result: FAILED. Not sure why.
