Strengths and weaknesses.?
What profile you’re targeting here in citrix.?
What do you do apart from coding and studies.?
How many apps have you published till date and why you didn’t publish the rest.?
Any shortcomings in our interview process.?(I told them, I didn’t like the HackerEarth platform on which they take tests. )

Tips/Advices:-
They were mainly looking for guys who had done lots of projects in software. In the whole interview process they only focused on my projects and fundamentals of java. They didn’t ask me anything that’s not in my resume. So, Don’t write anything in your resume that you’re not confident about. They just want you to have sound basic concepts.
