ServiceNow SSE
Summary
I interviewed for a Senior Software Engineer (SSE) position at ServiceNow, which included an HR screening and a Problem Solving/DSA round. I successfully solved the DSA problems within 30 minutes and discussed work culture, but I was ultimately rejected.
Full Experience
1.HR Screening
2.PS/DSA
1.Longest subarray of zero Sum
follow up : Print subarray
2. Zig zag traversal of Binary Tree
Solved with in 30 mins and discussed work culture in servicenow
Final Verdict: Rejected
Interview Questions (3)
Longest Subarray with Zero Sum
Find the longest contiguous subarray whose elements sum up to zero.
Print Longest Subarray with Zero Sum
After finding the longest contiguous subarray whose elements sum up to zero, print the actual subarray. This was a follow-up to the previous problem.
Binary Tree Zigzag Level Order Traversal
Given the root of a binary tree, return the zigzag level order traversal of its nodes' values. (i.e., from left to right, then right to left for the next level and alternate between).
