Hi Jacky, bit late to this, but I'd thought I could chime in here with a couple of my tips:
- Know your application inside and out – they will definitely ask you something about it.
- Research your interviewer (if you know who they are) – it helps you make questions which you can ask them at the end of the interview.
- Practice answering common interview questions – @Jaysen kindly listed out 260+ interview questions which you can see here.
- STAR method is key for competency questions like "tell me about a time you have demonstrated teamwork".
- If you have a specific firm you're interviewing for, have a look at the Interview Experiences to see if you can find any interview questions from that firm – try and identify which ones were asked every year.
- Separately, you can search for that firm's interview questions across the forums using the search bar in the top right of every page (right below your profile).
- Have friends and family (or even people on this forum, if you want) evaluate your answers – evaluation will only make your answer more complete.
- If you're doing a virtual interview, have sticky notes with bullet-points of your answers – this is so you have a quick reference point to your answers when you get asked questions.
- Side tip: Stick google eyes around your computer camera – this helped me keep my eyes on the camera rather than at the screen during interviews.
- Be yourself, be confident – they invited you for an interview for a reason, and that reason is because they see something in you and want to get to know you more, so show them who you are.
Hope this helps! 👍
