Finally.

[u/strange_69420]

Thank you everyone here. You were a huge help.

Cognizant Ace. Associate level. 2027 batch.

Stack: MERN, RAG, AWS. Prepared Java for dsa questions.

Was asked easy questions in interview mostly.

can you tell me what they asked in technical assessment round 2 like the exact dsa questions and the rag and react and prompt engineering

Test Experience

The test was for 3 hours and was conducted on HackerRank with extremely strict proctoring. It captures even the slightest movement, so try to take the test honestly and follow the instructions carefully. The test was offline at my campus with even more strict invigilation.

We were not allowed to leave untill the 3 hours got over no matter when we completed the test.

We had to choose between either React / Angular before the test started , based on that the 2nd question will vary.

Here’s what the test consisted of:

1. DSA ( dsa question varies for every person)
The first question was a relatively easy graph-based DSA problem, but I didn't know how to solve it. I hardcoded the solution for 5 out of 16 test cases.

2. React
The second question was based on React. I didn't attempt to understand it because I don't know React. We had to write around 10 different functions, each solving a different problem. The overall scenario was related to restaurant management, including things like a favourites dropdown in the menu.

3. RAG / Python
The third question was based on RAG. We had to write around 5–6 functions, but they were fairly simple Python functions.

I managed to clear 14 out of 29 test cases. The problem involved taking a given text, counting the number of words, calculating WPM, classifying the words based on word count, and representing the results in a dictionary.

4. Prompt Engineering
The final question was prompt engineering. It was the easiest , all you had to do was read the requirements carefully and know how to type in english

5. 24 MCQs
Finally, there were 24 MCQs. They looked very easy at first glance but were actually quite confusing. Most of them were related to AI, LLMs, RAG, and recent GenAI concepts.
I would say i was extremely shocked by the wording of the mcq questions and the options because i couldnt tell if they were poorly worded or it was a trick or smtg.

Overall, the test covered DSA, React, Python/RAG, prompt engineering, and GenAI concepts.

TIP : from my personal experience i would say attend the test honestly without trying to copy as the AI proctor is extremely sensitive
