Why you followed the praticular approach while solving a problem and at the end needed to give the time ans space complexity .
Question was a combination of
Round 2 (Design Round 2-3 hours):Design Database in any preffered language the Database should meet the basic constraints is is primary and length of stiring if varchar type and other .

One need ot follow the oops approach for creation of class , interface and design , also you need to write the code from scratch and you can decided the IDE and language but need to be fast in writing the working code.
Basic methods like insert(with constraints met like string length < 100 ), delete , search crete table, delete table, create database.
This round can be tiring .
Round 3 (Hiring Manager Round 40 Min ):This was one of the coolest round the person asked about the Behavioural questions and how you justify youserlf in an argument .questions related to current technology .
