Congratulations — your cover letter worked! Now comes the interview. This guide covers everything you need to prepare, from the moment you receive the invitation to the follow-up email after.

Phase 1: Research (2-3 Hours Before)

Company Deep Dive

  • Read the company's About page, mission statement, and values
  • Review their last 3 press releases or blog posts
  • Check their Glassdoor reviews (focus on interview experiences)
  • Look up the company on Crunchbase for funding history and growth trajectory
  • Follow them on LinkedIn to see recent updates and team expansions

Role Analysis

  • Print the job description and highlight every requirement
  • For each requirement, prepare a specific example from your experience
  • Research the typical salary range for the role in your location

Interviewer Research

  • Look up each interviewer on LinkedIn
  • Note their background, tenure at the company, and any shared connections
  • Prepare thoughtful questions specific to each interviewer's expertise

Phase 2: Preparation (1-2 Hours Before)

Master the STAR Method

Structure your answers using Situation, Task, Action, Result:

  • Situation: Set the context. What was happening?
  • Task: What was your responsibility?
  • Action: What specific steps did you take?
  • Result: What was the outcome? Use numbers when possible.

Prepare Your Stories

Have 5-7 strong stories ready that demonstrate:

  • Leadership
  • Problem-solving
  • Teamwork
  • Failure and learning
  • Technical expertise
  • Conflict resolution
  • Innovation

Questions to Ask Them

  • "What does success look like in this role after 6 months?"
  • "What's the biggest challenge the team is facing right now?"
  • "How does the company support professional development?"
  • "What's your favorite part about working here?"
  • "What are the next steps in the interview process?"

Phase 3: Execution (Day of Interview)

  • Test your tech: camera, microphone, internet connection (for virtual interviews)
  • Dress one level above the company's typical attire
  • Arrive 10 minutes early (virtual: join 3 minutes early)
  • Have water nearby
  • Keep your resume and notes accessible but not visible on camera
  • Turn off notifications on all devices

Phase 4: Follow-Up

Send a thank-you email within 4 hours of the interview. Keep it concise:

  • Thank them for their time
  • Reference one specific topic you discussed
  • Reiterate your enthusiasm for the role
  • Keep it under 150 words

Common Mistakes to Avoid

  • Talking negatively about past employers
  • Not having questions prepared
  • Rambling — keep answers under 2 minutes
  • Failing to follow up
  • Forgetting to send thank-you notes
