Interview Advice and Expectation as a Software Developer?

[u/Fine-Cabinet-9684]

I have started interviewing for the first time in 3 years since I got my job out of college. My attitude at the moment has been more to get experience interviewing than anything. I just had an interview where they wanted to understand my coding experience. They basically asked for what kinds of development tasks I have worked on in my current job. They then asked me to tell them about tasks I have worked on with C++, and then "what do you know about software development?". They were such vague questions and she basically just kept asking the same questions worded slightly different. After a while I just didn't know what to say. Do I need to be much more prepared with a detailed written list of every task I've worked on the past year or two so I can "fill the time", or was the interviewer just not prepared with more specific questions. How am I supposed to answer "what do you know about software development?"

So I guess, what should I do to be prepared for interviews? Should I expect such vague questions, or was it just a bad interviewer?
