Veritas visited our college for campus hiring. The CTC offered was 9.26 LPA. There were a total of 105 candidates eligible for the recruitment test. The selection process included an aptitude test, 2 tech interviews, and HR interview.
ROUND 1:(Aptitude+Technical test)
The aptitude test was on HackerRank.
It had 20 MCQs based on CS concepts, C/C++ output questions, oops concepts(constructor, inheritance, overloading, overriding), etc.
There were also 2 coding questions:-
Q.1 Write a function to detect a loop in the linked list. return “YES” or “NO”.
Detect loop in the linked list
Q.2 Write a function to delete all those nodes in the linked list which contain data greater than a value k. return head node.
My approach was to
1) Traverse the LinkedList using two pointers prev & curr.
2) When curr value is greater than k, make prev->next point to curr->next.
3) Delete curr node.
4) Make new curr point to prev->next.
5) Repeat till curr is not NULL.
There were some more edge cases to be covered.
Round 1 was easy. Around 30 students out of 105, were shortlisted for the Tech interview. All those who passed all the test cases of both the coding questions easily were selected, few with partial submission were also selected.
