Adobe | MTS 2 | Interview Experience (Frontend)

Hi, this is my first post on any platform sharing my recent interview experience for an MTS 2 Frontend role at Adobe. I went through five rounds, and I'm thrilled to share that I was selected!

Round 1: Technical (Frontend & DS Algo)

This round started with introductions, followed by questions on JavaScript fundamentals. The interviewer presented a scenario to gauge my understanding of the event loop rather than directly asking about it. We also discussed closures and React fundamentals. Towards the end, I was given two data structures and algorithms questions: one related to trees (medium difficulty) and another involving array manipulation (easy-medium).

Round 2: Technical (System Design & DS Algo)

After introductions, the discussion shifted to system design, specifically how we handle cache invalidation in my project. I then had to explain the end-to-end process of how our project serves millions of users daily, from deployment to the user's device. We also delved into in-depth questions about frontend optimizations I've implemented. Finally, there was another DS-Algo question, again related to trees (medium problem).

Round 3: Hiring Manager (Behavioral & DS Algo)

This was a hiring manager round. After introductions, I was asked to explain one of my projects that I'm most proud of and articulate why. Following this, I faced two more DS-Algo questions: one required me to code the bottom view of a binary tree from scratch, and the other was a binary search-related problem, similar to 'Aggressive Cows'.

Round 4: Senior Hiring Manager (Technical & Reasoning)

The senior hiring manager round began with introductions. I was asked to explain my current project in detail. This was followed by a frontend machine coding problem (medium difficulty) in React. After that, a reasoning problem was posed: 'A 4x4x4 cm cube is given; how many 1cm³ cubes can be cut from it?' The follow-up question was, 'If we paint that cube from all sides, how many of the cut cubes would have all 3 sides colored?' Finally, there was one more DS/Algo question related to trees (medium).

Round 5: Design & Architect

I had anticipated general system design questions like 'Design WhatsApp' or 'YouTube,' but the round started with a discussion about my previous interview experiences. The interviewer then asked about my project, specifically the impactful changes I was proud of. I had to explain the entire project flow in a drawing tool, essentially creating a high-level design (HLD) of my own project. We discussed various aspects like design choices and potential alternatives. There was also a discussion about why I hadn't used the Lodash library in my project, and I was asked to implement one of its functions. The last problem was to print the Fibonacci sequence without storing any numbers, meaning if I called `fib(10)`, it should print the first 10 Fibonacci numbers without using any storage. I approached this using recursion and some additional logic.
