*(Added on 22-09-2021)*

First they asked my preference and I said abstract algebra.

Then they asked two questions from the nbhm phd written test. One is prove the formula ” number of idempotent elements in Zn = 2^d”

And another one from linear algebra and I answered the question in written exam wrong but still they said to try there…

Then they ask

- What is class equation?
- What is the cardinality of center of a group of order 27? Explain it by the help of class equation.
- Number of Homomorphism from S3 to Z6? Explain.
- Let A,B are closed sets in R. Consider the set dist(A,B) defined by {|x-y|:x in A,y in B} = 0 then what can you say about the intersection of the sets A and B.
- One question from topology which I didn’t remember.

Suggestions:

If you are appearing nbhm interview try to read the proofs of the formula we generally use and prepare your nbhm exam questions..all of them

And whatever your preference can be…they ask question from real analysis and topology.

Thank you

Thank you very much for providing useful tips and updating us on events happening in Mathematical world.

**📚 (Our Question) Any Suggestions from your Side…**

Hello Sir…my suggestions are

One may clear the competitive exams but clearing interview is completely different. We need to have good knowledge of topics. Must read standard books (including proofs) like Bartle for Analysis, Gallian for Algebra, etc. Avoid random guess because one wrong answer would expose all your weaknesses. If you don’t know the answer them simply say I can try try and after try if could not get answer then say that you don’t know the answer… Logical implications must be sound.
