Here I am sharing few tips which will really help each and every student to clear his interview.
Why UK?
Compare with your home country (Cost, Duration, Fee, Entrance Exam, Value of degree, Standard of education, exposure) With evidence (Any website proof, Alumni review)
Why XYZ university?
Compare with home country, Canada, Australia (Course duration, pocket friendly fees, always focus on Modules) Use evidence (Skill development, Customize your course with optional modules)
Why XYZ course?
Compare with other Universities in UK (before comparing check the modules, similar fee, franking, location, cost of living, student satisfaction ration, MNC tie-ups)
Future career plans?
Relate it with your previous profile (Academic/Job duties)
Use evidence (Naukri.com, LinkedIn, Monstor.com, Glassdoor)
Choose any 2 modules to relate it with your previous study, current job demand, competition in market, and CTC in MNC (Home country)
Be genuine, do your own research. Never copy answer because every student have different profile, different future goals even after same course in UK.
