Nowadays many Multinational companies ask follow-up questions during the interviews like
Technical Round: :- 2Sum Problem
-You came up with brute force solution
-Next, you came up with an optimized solution
-Next, you completed the dry run and done coding the finalized solution.
Now here comes the tricky part!
If the Interviewer ask you 3Sum Problem and you just have 5 minutes extra and you just have to explain the approach or if you have time then code.
This is important for a better chance to land your DREAM JOB.
But sometimes these follow-up questions become very tricky because we know the first problem but how to connect the question with the follow-up.
