Those questions were very important questions. In fact the 1st one was very interesting one. They may not expect the "real answer" from you but how you answer does the trick.
For eg, in one of your recent projects you would have had some technical difficulties, you can talk about how you or team overcame that issue.
Be genuine. don't say "I only did this other team members couldn't do it".
This is very common questions could be asked during technical rounds too.
