Hi @durrrr and @kuboring. congrats for being selected for 1st round of interview.
@durrrr may i know when did you submit your application?
regarding the tips u should be prepared very well about whatever you have mentioned in your resume. and also be prepared to answer any question about SIA or its subsidiaries and current affairs. especially questions like why you wanna be a pilot and they may ask you to prove ur passion for flying. you need to justify and convince them how badly you wanna be a SIA pilot.
