Waiting for result
The interview consisted of two main parts: coding and behavioral questions.
Coding Challenge:
-
The first part was to solve a problem based on data structures. They presented a scenario where you had a tree-like structure and needed to implement a function that could find the maximum depth of the tree. They were looking for efficiency and clarity in your approach.
-
The second part of the coding challenge involved understanding and implementing a caching mechanism similar to LRU cache. You had to explain your thought process as you coded the solution.
The interviewers asked follow-up questions related to the choices of data structures and algorithms you opted for, along with time complexity analyses.
Behavioral Questions:
- Tell me about a time when you faced a technical challenge on a project. How did you approach it?
- Describe a situation where you had a conflict with a team member. How did you handle it?
Overall, the interview was very technical but also focused on cultural fit and interpersonal skills. They were interested in understanding how I worked within a team and tackled problems creatively.
