Interview
Pretty normal. Just grind the core java and spring boot topics. Focus on most asked interview questions. Nothing special to be honest. Sound confident. Otherwise it might give bad impression. That is all there is to it.
Easy did not any different or difficult questions and one coding question as well which is just showing repeated alphabets and their count as well for the coding question.
That's all the interview i remember which is an easy interview
