I only made it to the coding assessment interview.

It was four questions on CodeSignal, where the first two questions were very easy, and the last two very difficult. The time limit was an hour and 10 minutes.

I recommend doing a ton of LeetCode problems leading up to it, and completing all the practice questions on the CodeSignal platform. I was only able to make it through half of those questions before the exam, which is why I did well on the first half.

Given a character matrix and an array of words, find the total number of occurrences for each word in the matrix.

NOTE: When finding a word, you can only switch directions once for each time you search the matrix for that word.

Example:

a b c d e r a c e a b b s e a

On row two, let's say the word we are looking for is "racecar." We can change directions once after visiting 'r', 'a', 'c', and 'e' to get 'c', 'a', and 'r' again.
