Compass Software Engineer I interview questions

I had a junior software engineer at Compass, it was 3 rounds on-site at same day in 3 hours time frame, one was behavioural round (which they prioritize alot), second was DSA coding round in which they give a leetcode advanced graph "HARD" question and I wasn't expecting that hard question for a junior software engineer role, and third was the pair programming in which there was a python script and I was supposed to find a bug in the script and solve it.

Debugging, technical, then behavioral. I had been given two language options for the debugging portion (Java or Python) during the phone interview then when I went to the onsite there seemed to be a miscommunication because the interview said I could use JS since I was applying as a frontend engineer. The debugging was pretty doable, the behavioral was odd but fine.
