Copied the question straight into Claude, pasted the output back, and then just told the interviewer what I did and why.
Start by clarifying the problem constraints and edge cases, then outline your algorithm and its complexity before coding. Write clean, modular code with meaningful variable names, and test with sample inputs and edge cases while explaining your reasoning.
Pro tip: Verbalize your thought process continuously, especially when stuck, and proactively discuss trade-offs between time and space complexity to demonstrate engineering maturity.
Restate the problem in your own words, ask clarifying questions about input ranges, edge cases, and expected output format.
Discuss possible algorithms (e.g., brute force vs. optimized), choose one, and analyze its time and space complexity.
Write clean, well-structured code with comments, using appropriate data structures and handling edge cases.
Walk through sample inputs, test edge cases, and debug any issues while explaining your reasoning.
If time permits, discuss potential optimizations or alternative approaches and their trade-offs.

This came up as context for why I was so fed up going into this screen.
Start by defining a TLB as a hardware cache that stores recent virtual-to-physical address translations, then explain its role in speeding up memory access by avoiding a full page table walk. Use an analogy like a 'cheat sheet' for addresses, and connect it to performance in systems with virtual memory.
Pro tip: Mention that TLB misses can be costly and that modern CPUs use multi-level TLBs; relate this to real-world performance tuning in high-frequency trading or banking systems where memory latency matters.
State that a TLB is a small, fast cache that holds recent virtual-to-physical address translations, part of the memory management unit (MMU).
Describe how it reduces the time to access memory by avoiding a page table walk for every memory reference, leveraging locality of reference.
Outline the process: on a memory access, the CPU checks the TLB; if hit, translation is immediate; if miss, it walks the page table and updates the TLB.
Highlight that TLB hits are fast, misses incur latency, and context switches may flush the TLB, affecting performance.
Relate TLB to virtual memory, caching, and system performance, especially in latency-sensitive applications like banking systems.
