Hey everyone, For those giving/given multiple interviews, what’s your take on this? Does using C++ for LLD interviews put you at a disadvantage, even if you know multithreading and concurrency well, since most interviewers know and seems comfortable with Java only, for these concepts? I have been using C++ for dsa since a long time now and have learned lld and multithreading in cpp only and I haven’t learned Java till date. At this point, I don’t feel like investing time in learning a new language. I believe fundamentals and concepts matter more, especially with AI tools helping with syntax. I’m more focused on system design, architecture, and real-world scalability problems now. Should I still learn Java for interviews or stick with C++? Would appreciate your thoughts.
