FAQ

Q: How hard are Big Tech software engineer interviews?

Q: Should I focus on LeetCode or system design?

A: For L3-L4 (junior/mid), LeetCode matters most (60-70% of evaluation). For L5+ (senior), system design becomes equally important. Balance both, but weight based on your target level.

Q: What programming language should I use in coding interviews?

A: Use whatever language you're most fluent in. Python is popular for its conciseness, but Java and C++ work equally well. Interviewers care about problem-solving, not language choice.
