Initial call with the recruiter where she went over the role and asked about my background.

Next, a pair programming exercise with another Frontend engineer followed. The exercise was probably of medium difficulty, similar to something you'd find on LeetCode.

However, the algorithm didn't test for anything mentioned in the job description, so perhaps they wait until the onsite to assess Frontend knowledge.

I was able to come to a solution after getting stuck a few times.

Separating a string by only allowing N characters on each line. An entire word must fit on one line. If you have additional spaces remaining, those must be distributed through the current line.
