Coding System Design
They asked me to build a HashMap using an array and linked list (or vector) for buckets, and to handle collisions through chaining. Then, about ordered maps keeping sorted keys (tree) versus unordered maps being hash-based with no order. Finally, ACID properties via WAL logs, commit flush, crash-safe storage, and locks for consistency.
Confirmed questions3 questions
- Design and implement a HashMap, detailing its bucket structure using an array and linked lists, and explaining collision resolution through chaining.
- Contrast the characteristics of ordered maps, which maintain sorted keys using a tree structure, with unordered maps, which are hash-based and do not guarantee key order.
- Explain how ACID properties are ensured in a database system, referencing the roles of WAL logs, commit flush, crash-safe storage, and locking mechanisms for maintaining consistency.

Technical System Design Coding Behavioral
There were three rounds. The first one was purely technical, done by a SDE 3. He was a chill, wholesome guy and made me feel comfortable. We started by discussing my projects, the reasoning behind them, and how I implemented them. Then we dove into Websockets and authentication. After that, I was asked to design a rate limiter for an API gateway and optimize it using Redis. For DSA, there were two relatively simple questions. One involved strings and arrays, which I solved and optimized, although the interviewer mentioned Tries as a potentially better approach, which I considered. We also touched upon some basic SQL and NoSQL concepts, networking, and throttling. The round ended with a general chat about culture and expectations. I felt good about this round and was confident for the System Design one. However, I didn't clear it. My guess is that they are looking for absolute clarity and near-perfect answers, and any confusion or indirectness can be detrimental.
Confirmed questions2 questions
- Design and optimize a rate limiter
- Search for 1D vectors within a 2D character grid, corresponding to given strings, with modifications and new constraints introduced iteratively.

“Find the total count of 1s in a matrix that is sorted row-wise with 1s and 0s”
Read reports →“How to find the total number of set bits in all numbers from 1 to n?”
Read reports →“What is the length of the longest neat subsequence of a given array `a` of `n` integers? An array is neat if it's formed by concatenating blocks. An empty array is neat. A subsequence is formed by deleting elements from an array.”
Read reports →“How do you delete a node from a linked list given only a pointer to that node?”
Read reports →“Given a number N and a linked list of length L with duplicates, find the first N Fibonacci series terms, and if any value from the Fibonacci series is present in the linked list, remove all occurrences of it.”
