Frequently asked questions

How should I prepare for a Web Developer interview?

Research the company and read the job posting line by line so you can connect your experience to what they need. Practice your answers out loud, prepare two or three questions of your own, and plan your route so you arrive early and calm.

What should I wear to a Web Developer interview?

Dress one step above the everyday dress code for the role. For office roles that usually means business casual; for trades, service, and warehouse roles, clean and neat matters more than formal. When in doubt, ask the recruiter.

What questions should I ask the interviewer?

Ask what a typical week looks like, how they measure success in the first 90 days, and what the team is like. Their answers tell you as much about the job as your answers tell them about you.
