KLA Software Engineer Summer Intern – 2023
First Round ( Coding Round):
- There are two questions in this round and the time given is 90 min, which is conducted in HackerRank.
- The first question was like a standard question based on BFS, but there are some more glitches added.
- The first question on brief: there is a 2D matrix filled with 1s, 0s, and walls. Given start and destination indices where you have to tell whether a person can able to reach to destination from start. The person can travel in any of the 4 directions. Also, he can break the wall if he visits the wall at least twice, now the wall will become the way which is 1. Where 1 means the way, and 0 means no way.
- The second question on brief: I guess no logic is needed for this just solve according to the given question. ( Unfortunately, I haven’t solved this fully but solved it partially – made a simple mistake) this question is for 40 pints.
Tips:
- Watch the striver graph playlist on youtube. This question carries 160 points. ( I have fully solved this in the first 40 min).
- You had to know C++ STL.
I got selected for the next round. Few people who did the second question fully and partially the 1st also got selected. From our class, 25 members were selected.
Round two (in-person workshop):
Round 2 is an in-person workshop that is conducted in their office.
- After having breakfast at the office, the workshop started at 9 am.
- They explained the problem statement and assigned a mentor for each of the 5 members (not a team-based one).
- There were 7 milestones in the problem. each milestone is linked with the other. It is an open book workshop and the mentors and the staff were so friendly and so kind to us.
- It went until 5:30 pm, and 7 members were selected.
I couldn’t make it in round 2. But this is a wonderful experience for a person like me since this was my first in-person workshop.
Thanks, KLA.
