Round 1 : Regarding performance, accessibility, state management, CSR, SSR , SSG, security Round 2: The Lead engineer wanted mean to open a create a new react project. He expected that I knew all the commands and shouldn't take any help from google. It was the most absurd interview I have ever attended. The interviewer was Sunil something and was very rude. He was asking questions you wont even ask freshers. It was like he was showing off his knowledge in React.

HR round - standard questions on why you want to change, describe your current role, any challenges you faced etc. Technical round - all detailed questions on current project architecture, .net core basics (middlewares, service lifetimes), web API - put vs. post, how do you handle authentication & authorisation, SOLID principles, design patterns - explain which ones you implemented, logical questions, some SQL queries around joins like if you have 2 tables, get the table from the right table & also from the right table even if no matching values present in left. Linq query - Write an example of how to return a complex object. Write a program to calculate the sum of the prices of different flowers passed as a list object using OOPs principles. for example: The user will provide flower quantity, and price, input in the form of a List, (10 lilly, 20 roses). Some questions on Azure, but only basics. Manager (Technical) round - The same questions as above, but in detail on how you implemented everything. Web API - If you have to implement logic for all the APIs and not write redundant code - how will you do? Explain a few design patterns, and repository pattern and how you implemented them in the project.
