An interview is not an exam. It is a conversation to see whether you and they fit. But that conversation goes far better when you have prepared for it.
Before:
- Spend ten minutes reading about the company. What exactly do they do? Who are their customers? If there is no website, ask around. Anything you learn lets you ask a sharp question at the end.
- Read the advert again and pick out three things they are asking for. Have a real example ready for each, from work you have actually done.
- Prepare your answer to "tell me about yourself". Two minutes, not ten. What you do, the best thing you have done, and why you are here today.
- Prepare an answer for "what is your biggest weakness". Do not say "I work too hard" — everyone says it and nobody believes it. Name a real one and what you do about it.
On the day:
- Arrive fifteen minutes early. If it is online, open the link five minutes early and test your sound.
- Clean and tidy beats expensive.
- If you do not understand a question, ask them to explain. That makes you look attentive, not the opposite.
- When they ask about a problem you faced, tell it in order: what the problem was, what you did, how it turned out.
At the end they ask "do you have any questions?". Never say no. Ask something like: what does a normal day in this job look like? What is the biggest challenge for someone new in their first three months? Those questions say you are thinking about the work itself, not only the salary.
Afterwards, send a short message thanking them for their time. It is a small thing, and few people do it.
