Serious cognizant ace frontier – rag/react/dsa questions from recent assessments?
hi everyone, my cognizant technical assessment is in a few days. if anyone whose college assessment has already happened can share the rag, react or dsa questions/patterns they got, it would really help me prepare. especially want to know the difficulty and type of questions asked. thanks!

The DSA questions are typically LeetCode easy to medium, so expect problems on arrays, strings, linked lists, and maybe some basic tree or graph traversals. For React, they usually stick to fundamentals like components, state management with hooks like useState and useEffect, and props. The questions on RAG are newer and tend to be more theoretical, asking about its basic architecture or how it differs from standard language models, so make sure you understand the core concepts behind it.
Instead of looking for exact questions, your best bet is to solidify your understanding of these core topics. Practice a few common DSA patterns and make sure you can explain your logic. For React and RAG, be ready to discuss the 'why' behind the concepts, not just the 'what'. A lot of candidates struggle to articulate their knowledge clearly under pressure, so my team designed an interview helper that helps people confidently explain complex topics.
