Are you a team player? 

Give me an instance where you demonstrated your team player ability.
This question is about working in a team. You can narrate an instance where you and your colleagues worked together to achieve a difficult task which would not have been possible if you all did not contribute. Instances related to meeting delivery timelines are typically such scenarios. However, if you have been part of an actual instance nothing can be like it.
Else, you can refer to this example. Your team was working on a change request. The delivery timelines looked difficult to meet because of some issues. On top of that, one of the testers fell sick. Without a tester, meeting the deadline was impossible. So, you decided to participate in the testing to help the team. This way, your team was able to meet the deadline.
If you have worked in an agile environment, do mention that your project followed agile. One must be a team player in an agile environment for a project to be successful. This will give weight to your profile.

I had an opportunity to demonstrate my capabilities at supporting the strategic direction of
my employer while I worked for the Department of Transport, when for six months I ‘acted up’
in a manager position in the Case Assessment Team.
When I started in this position the volume of files that the team was dealing with was very high
and causing considerable stress and tension. A big concern for senior management was that our
team had one of the highest per-employee rates of sick leave, which was thought to be the
result of stress.
Despite the problems, I was told by senior management that it’d be fine if I just kept things “in
a holding pattern” until the manager position was filled on a permanent basis. However, I saw
an opportunity to make my mark by improving our processes.
Thinking strategically, I thought that I could harness the information they gave me to devise
faster and more efficient ways of handling our files. I spoke to every member of the team
individually and asked for three ideas for how to better handle the caseload.
I then harnessed the information presented: my strategic judgement was that of the ideas
presented, the best one was to create a series of template paragraphs that would apply to
around 80% of our cases and make the process of drafting decision letters much faster. I
allocated the coordination of this task to a junior staff member with a flair for drafting, as I
judged that she had both the time and the best skill set to carry out this task.
This was a big success. Our speed at dealing with run-of-the-mill files improved dramatically,
giving the team breathing room to allocate sufficient time to the more complex files. Crucially,
our sick leave rates went down to below the Departmental average and have stayed that way
to date.
