How to do well in an interview
Before:
Look at the workplace's website for 5–10 minutes. Know what they actually do.
Think about why you want this opportunity. If you don't know, they'll know you don't know.
Prepare 2–3 questions to ask them. Shows interest. Examples: "What does a typical day look like?" "What do you like most about working here?" "What would you want me to be doing well by the end of the placement?"
Dress one level up from how you'd dress for the actual job. Not a suit unless it's a corporate setting — clean, neat and respectful is fine.
Bring a printed resume even if you've emailed it.
During:
Arrive 10 minutes early (not just on time).
Firm handshake, eye contact, smile. Use the person's name when you greet them.
Phone off and away — not just on silent.
It's okay to say "let me think about that." Better than waffling.
Be honest about what you don't know. They aren't expecting an expert.
After:
Send a thank-you email the same day or the next morning. Two sentences. Hardly anyone does this. The few who do stand out.
If they say no, ask for feedback. "Anything I could have done better?" Most people will tell you. It makes the next interview better.
