It was 1 coding question with 10 test cases. They asked a question based on binary search. I got 3 hrs to clear that test. I went in as a campus fresher. For lateral joinees, it is a much more difficult question that you have to clear in 4hrs.

Q1. What's the best way to find majority element in an array?
Ans. 
The best way to find the majority element in an array is by using the Boyer-Moore Voting Algorithm.
• Initialize a candidate variable and a count variable.

• Iterate through the array and for each element:

• - If the count is 0, set the current element as the candidate.

• - If the current element is the same as the candidate, increment the count.

• - Otherwise, decrement the count.

• After the iteration, the candidate will be the ...read more
