Round 1
Questions: 1 Easy and 1 Medium Leetcode question on Bitwise manipulation and backtracking. Solved both optimally.
Candidate's Approach
The candidate solved both questions optimally, demonstrating a strong understanding of data structures and algorithms.
Interviewer's Feedback
No feedback provided.
Round 2
Questions: Design a multi-tier elevator system. Given some information, you need to come up with class diagrams. The candidate created class diagrams and applied OOD patterns such as the strategy pattern for elevator movement and the command pattern to process requests. The candidate was also given a choice of algorithms like FIFO, SCAN, and Priority weight.
Candidate's Approach
The candidate successfully created class diagrams and implemented various OOD patterns for the elevator system design. They effectively utilized algorithms for request processing.
Interviewer's Feedback
The interviewer was very satisfied with the candidate's performance and the solutions provided during the design round.
