Your question is Core Cryptography Algorithms. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Discuss basic cryptography algorithms.
Cover the purpose and basic operation of symmetric encryption, asymmetric encryption, hashing, message authentication codes, digital signatures, and key exchange. Explain when algorithms such as AES, RSA, SHA-256, HMAC, ECDSA, and ECDH are used, and identify the security property each provides.
The interviewer is checking whether you can distinguish confidentiality, integrity, authentication, and key establishment rather than simply list algorithm names. Keep the discussion at the algorithm and practical usage level, without implementing cryptographic primitives or discussing Qualcomm-specific products.
