I applied online through their career portal and received an email requesting a technical phone interview a week later. A HackerRank link was to be shared with the interviewer.

During the phone call, the interviewer inquired about my resume and background before moving on to the technical question. He was not particularly helpful in guiding me toward a solution. He coughed frequently, without excusing himself, and was generally uncommunicative.

I requested clarification on some points, but he declined to respond.

I received a rejection email the following day.

Given a string, for example, 'whatismyname', which initially has spaces removed. The task is to insert spaces into the string where a valid English word exists. You are provided with a 'dictionary' containing valid English words.
