Hi everyone,

I’m a Java backend developer with around 5 years of experience and I have some basic knowledge of AWS (like EC2, S3, a bit of IAM), but I haven’t worked deeply on it in real projects.

I’m preparing for interviews now, and I’m a bit confused about how much AWS I should know and what kind of questions are usually asked.

Can anyone suggest?

What AWS topics are most important for Java backend interviews?

I don’t want to go too broad and waste time, so looking for something focused and practical.

Thanks in advance.
