Expedia Group Software Developer interview questions

Received an interview for an online coding challenge and completed all problems near optimally as they were ones that I’d done on hackerrank before. Received a second email saying I was still under consideration and they would be in contact within 4 weeks after taking the initial interview. Tried emailing several times and wasn’t answered until the 4th email stating they were no longer interviewing for this position this year. Terribly inefficient and no communication at all. Even if I did get offered a job from them, I wouldn’t take it after seeing how poorly they execute the interview stages. First impressions are important and their’s was abysmal.
