Intuit interview questions

The interview was outsourced to Uptime Crew. Standard structured process of 5 rounds (Asessment(4 MCQs, 1 LC, 1 SQL, 1 Bash Script(this one is tricky but majority of the solution you will find in the question so read it carefully and understand) ) , Phone Screen, Build Challenge, 1:1 Tech Screen) the final 5th round is Managerial Interview with Intuit team member

I was totally ghosted after my interview. After speaking with the recruiter, she set up the formal interview with the hiring manager on the Benefits team. The hiring manager was 20 minutes late. And her reason was because she "didn't see her calendar notification". The interview overall wasn't difficult. But a week after, I sent a follow-up email to the recruiter... Silence... No response, nothing. I thought I at least deserved an update especially since I was patient enough to wait for the late manager.
