Johnson Controls interview questions

I had a pre-interview call with a Talent Acquisition Partner, who provided insights into the structure and reassured me that the interview wasn’t something to extensively prepare for, though knowing a bit about the company was advised. The interview, scheduled for 30 minutes on Teams, lasted 55 minutes. I expected a panel of two but was surprised to find four interviewers. The process included general and technical questions, covering topics like debugging in IDEs like Visual Studio Code, operating systems, and teamwork. It also featured two technical challenges: identifying a heavy coin from a set using a scale and checking if two strings are anagrams. One interviewer was in a noisy environment, which made concentration difficult. Despite following up after the interview, I received no response, leaving me feeling completely overlooked. The lack of communication was disappointing and unprofessional.
