Apply online, got sent a link to an online assessment with four parts. First part was a coding interview with two questions. Honestly I had no idea how to answer them, but I posted them below.
Hour and a half to complete the coding questions. Three other parts to the assessment, I bombed the coding questions

1. Random Walk Card Game:
consider the following game. Beginning with a deck of even size = N cards that are half red and half green (N/2 each), you begin drawing cards. For each red card, you win $1 and for each green card you lose $1. You may stop at any time. What is the value of this game to you assuming you play optimally? Write a program that computes this value.
Hints:
consider recursion

Updates are:
