It was a technical interview. It started with some questions about my background. And then I was asked a coding question, and I was asked to analyze the time complexity and space complexity
Focus on solving LeetCode hard-level problems
Analyze and discuss optimization techniques for each problem
Dive into the time complexity of different solutions
Leave some time at the end for any questions or clarifications
Ho presentato la mia candidatura tramite segnalazione di un dipendente. Ho sostenuto un colloquio presso XTX Markets
Colloquio
Phone call screening (~30 mins, voice only).
I was asked around 20 general questions about C++, compiler and OS architecture.
Interview was really fast paced, just to check the knowledge, no time to think or remember.
Domande di colloquio [1]
Domanda 1
-RAII
-C++ pointers
-memory alignment
-vTable, virtual functions
-variadic templates, emplace_back method (how it works with unique pointer, variadic templates)
-map, unordered map (how implemented, what advantages/disadvantages each one has)
-hash functions (when used, what's important about hash function definition)
-floating point numbers (how implemented, common problems with them)
-cache (how it works, what is cache line, prefetch, what are the modern cache architectures and one more question about some cache technique I wasn't familiar with)
