Dear Applicant Thank you for your application for the BU PhD Studentship titled Ecosystem service provision in dynamic heath landscapes. Your application is currently being considered and we will be shortlisting later in April, with interviews for shortlisted candidates to be held in late April / early May. In the event that you are shortlisted, please would you let me know your availability for interview during this time. With thanksLouise Louise PearsonResearch & Programmes Administrator School of Conservation SciencesChristchurch House, Room C136Bournemouth UniversityFern BarrowPooleDorsetBH12 5BBUKanybody who can guide me that what could they ask me during my interview for PhD studentship

I'd probably wait to see if you're shortlisted before getting concerned about what they're likely to ask you in the interview.
For the time-being you might want to scan the forum; there are a great many similar (general) questions which have received responses.
In sum:
- why do you want to do a PhD?
- why do you want to come to this University?
- what is your relevant research experience?
etc...
