Summary

I completed the Online Assessment which consisted of two coding questions. The assessment focused on code completeness and handling edge cases.

Details

The OA consisted of two coding questions, with no behavioral questions. The first question focused on basic data structures and string manipulation. The second question was more complex and required careful consideration of logic and edge cases. Both questions were LeetCode medium difficulty. While not directly template-based, familiarity with LeetCode problems is beneficial.
