Real Interview Questions I Faced

Coding and Algorithms

1. Memory Allocator "Here is a memory management problem: You have a 32-bit array where each element stores 64-bit data. Implement allocate() and free() functions without using any additional memory space."

2. Decaying Attention Implementation "Write code to implement 'decaying attention,' defined as:

Attention=softmax(QKT+b)V

Where b is the absolute difference between the indices. After implementing the layer, write the training loop using the provided data and model setup."

3.Formal (Written/Coding Prompt) Given three separate log files, representing Day 1, Day 2, and Day 3 respectively, find all users who generated more than 10 error logs on each of the three days.

The log data is provided as a stream of pairs (e.g., User1, 2, User2, 20, User1, 6), where a user may appear multiple times within a single file."

System Design

4. Photo Viewing App "Design a scalable photo viewing app. Focus on the practical aspects, such as how you would handle on-call rotations and system monitoring. You can skip the discussion on the news feed or timeline features."

Hardware & AI Architecture

5. GPU Architecture & Optimization

FAQ

Will Linkjob AI be visible if the interviewer asks me to share my screen?

Not at all. It integrates deeply with the operating system to render its overlay directly at the hardware layer. Because it operates independently of standard window capture processes, it remains completely invisible during screen sharing. The interviewer won't see a thing, so you can share your full screen with complete confidence.

How long did it take to hear back after each round?

I usually got a reply within one week. Sometimes, I waited a bit longer. I checked my email daily and stayed patient.

How should I manage my time during the coding interview?

I found time management critical, especially since most tasks were heavy implementations squeezed into 60–75 minutes. A single problem often split into sub-parts, so I really had to pace myself. I made sure to clarify and plan first, always prioritizing working code over getting stuck on micro-optimizations
