EarnIn interview questions

How to implement a HashMap without using the HashMap in Java?

All the interviewers don't know how to interview. They also don't seem technically strong. That's understandable as most technically strong people are in Faang. Most interviewers asked questions and never bothered to take note or share a document as it was remote. I opened Google doc and shared my screen. Also, I had to keep asking if they are ok with you what I am doing. Bad communication! Onsite 1. Design a local library. Onsite 2. Asked if 1st interviewer asked library, I said yes.. so asked some banking routing no and interview was done in 20 mins.. she said she had nothing else! Onsite 3. Cultural interview from new soft engineer who was customer support earlier. When was the last time you asked for help? And some other random stuff Onsite 4. A version of LCS I solved in n2 and they said it was brute Force! Design a restaurant and menu design question Onsite 5. Design Twitter like system. During the process he said he doesn't know how to implement it, then how is he going to assess me? I had to follow up after interview.
