What are 5 things you should do before an interview?

The upshot

A teen who researches the company and rehearses aloud is stacking the deck: Boys & Girls Clubs of America says preparation signals genuine interest and initiative — something 40% of hiring managers spot in the first five minutes.

Research the company and role thoroughly

Study the company website, read the job description again, and note what the role actually involves. The Youth Job Center (career development nonprofit) advises candidates to research the company’s mission and recent projects. This isn’t busywork — it gives you material to tailor your answers.

Practice answering common questions aloud

Understood (learning and attention resources) recommends practicing first with a parent, then with another adult you’re less close to, to reduce fear and build confidence. Saying answers out loud — not just thinking them — rewires your brain for fluency.

Plan your outfit, route, and logistics

Lay out your clothes, check the route, and set an alarm. More than one teenager has lost a job offer because they showed up looking like they just rolled out of bed. LinkedIn career advice (professional networking platform) suggests organizing documents, hygiene, and transportation plans the day before — not the morning of.

Prepare thoughtful questions to ask the interviewer

Asking questions shows you’re engaged. CareerVillage (peer career advice platform) suggests asking about daily activities and what the previous employee did well. It flips the script: you’re evaluating them too.

Review your resume and key talking points

Boys & Girls Clubs of America (youth development organization) says to have copies of your resume or work samples ready. Match your skills and passions to the job description so you can explain why you’re a strong fit — without reading off paper.

Bottom line: The implication: Preparation isn’t just about knowing facts — it’s about reducing cognitive load during the interview itself. When you’ve rehearsed logistics and answers, your brain can focus on connection, not panic.

What are the 5 P’s of interviewing?

The catch

Many guides list 5 P’s, but exact labels vary. The core is consistent: loose one P and your candidacy falters because hiring managers CNBC (citing Harvard researchers) show that the most common mistake job seekers make is failing to network and follow up — a direct violation of the “Post-interview follow-up” P.

Preparation – research, resume, logistics

Study the company, reread the job description, and organize your materials. The Youth Job Center (career readiness nonprofit) says preparation includes bringing resumes, references, and a pen. It’s the foundation everything else rests on.

Practice – mock interviews, STAR stories

Boys & Girls Clubs of America recommends practicing with a friend, family member, mentor, or in the mirror
Use the STAR method (Situation, Task, Action, Result) for behavioral questions

Presentation – body language, attire, tone

First impressions happen fast. The Boys & Girls Clubs of America (youth development organization) notes that silencing your phone and keeping it tucked away is a small signal of respect. Dress neatly — even for entry-level roles — and sit upright.

Punctuality – arriving early shows respect

Arriving at least 15 minutes early is the standard recommendation for teen interviewees from Boys & Girls Clubs of America. Late arrival is consistently ranked as one of the top deal-breakers for interviewers.

Post-interview follow-up – thank-you note, reflection

A thank-you note or email within 24 hours reinforces your interest. Boys & Girls Clubs of America (youth development organization) recommends this step. CNBC (citing Harvard researchers) highlights that failing to network or follow up is the most common mistake job seekers make.

Bottom line: The pattern: The 5 P’s aren’t just a checklist — they form a cycle. Preparation feeds practice, practice improves presentation, punctuality buys goodwill, and follow-up turns a good meeting into a lasting impression.

What are the 10 most common interview questions?

Why this matters

A hiring manager at a busy retail chain might interview 10 people in a day. The candidate who answers “Tell me about yourself” with a tight, relevant story rather than a rambling life history has already won the comparison — because Understood (learning and attention resources) says practice reduces fear and boosts confidence.

Tell me about yourself

This is your 60-second commercial. Understood (learning and attention resources) includes this as a common practice question for teens. Keep it brief: who you are, what you’re looking for, and one strength that matches the role.

Why do you want to work here?

Show you’ve done research. Mention a specific project, mission point, or company value. The Youth Job Center (career readiness nonprofit) says studying the company website is essential preparation for this exact question.

What are your greatest strengths?

Pick a strength directly relevant to the job. If the role involves customer service, talk about patience or communication. Back it up with a brief example — ideally using the STAR method.

What are your weaknesses?

Choose a real but fixable weakness, and explain how you’re working on it. “I sometimes get nervous speaking in groups, so I’ve been practicing with friends and in front of the mirror.” CareerVillage (peer career advice platform) suggests being honest about limited experience but showing eagerness to learn.

Tell me about a time you handled a challenge (STAR)

Behavioral questions are best answered using the STAR method. Understood (learning and attention resources) recommends practicing with specific stories — even if they come from school, clubs, or volunteering.

Where do you see yourself in 5 years?

Employers ask this to gauge ambition and retention. A safe answer connects to the role: “I’d like to grow into a leadership position in this field.”

Why did you leave your last job?

Keep it brief and positive. “I was looking for more growth opportunities” works. Avoid negative comments about former employers — it’s a red flag for professionalism.

How do you handle criticism?

Show that you’re coachable. “I listen carefully, ask clarifying questions, and use feedback to improve.” Boys & Girls Clubs of America (youth development) notes that employers value soft skills like communication and willingness to learn.

Describe a time you worked in a team

Use a specific example from a group project, sports team, or volunteering role. Outline what you contributed and what the team achieved.

Do you have any questions for us?

CareerVillage (peer career advice platform) advises asking about daily activities and what the previous employee did well. Not asking questions signals disinterest.

Bottom line: The trade-off: Authentic answers can feel vulnerable — but rehearsed scripts sound hollow. The middle ground is preparing talking points, not memorizing full answers, so you stay natural while covering key ground.

What are 5 things you should not do during an interview?

The trade-off

You might think asking zero questions makes you seem agreeable. In reality, it signals disengagement — and the CNBC (citing Harvard researchers) analysis shows that failing to engage is among the most common mistakes job seekers make.

Arrive late or unprepared

Arriving late is one of the top deal-breakers for interviewers. Boys & Girls Clubs of America (youth development organization) recommends arriving at least 15 minutes early. Being unprepared — not knowing the job description or company — is equally damaging.

Speak negatively about previous employers

Negative comments about past employers raise red flags about professionalism and attitude. Even if you had a terrible experience, frame it neutrally: “I was looking for a different fit.”

Fidget, slouch, or avoid eye contact

Poor body language can undermine even strong answers. Sit upright, make natural eye contact, and keep your hands still. The Youth Job Center (career readiness nonprofit) says gum is not professional — nervous habits like chewing gum or tapping are also distracting.

Give vague or rambling answers

Vague answers suggest a lack of preparation or confidence. Use concrete examples and specific details. The STAR method helps structure your response without rambling.

Fail to ask any questions

CareerVillage (peer career advice platform) advises asking thoughtful questions. Not asking any questions shows disinterest in the role and company.

The implication: Each of these mistakes erodes trust in a different way — lateness says you don’t respect their time, negativity says you’ll be a difficult colleague, vagueness says you didn’t prepare. They compound quickly.

How should a teenager prepare for an interview?

What to watch

Teens who walk in wearing a wrinkled hoodie and chewing gum are competing against peers who researched the company and dressed neatly. The gap isn’t talent — it’s preparation. Boys & Girls Clubs of America (youth development) says employers value soft skills like punctuality and communication over technical experience.

Highlight transferable skills from school, clubs, and volunteering

You don’t need paid work experience to have relevant skills. Team projects show collaboration. Club leadership shows responsibility. Volunteering shows reliability. Understood (learning and attention resources) recommends thinking these through before the interview.

Dress neatly even for entry-level positions

First impressions matter. A neat button-down shirt or blouse and clean, closed-toe shoes work for most entry-level roles. The Youth Job Center (career readiness nonprofit) emphasizes that looking professional communicates respect for the interviewer and the opportunity.

Be honest about limited experience but show eagerness to learn

CareerVillage (peer career advice platform) suggests being honest about limited experience while emphasizing willingness to learn. Employers of entry-level staff often hire for attitude and train for skill.

Prepare examples of teamwork and responsibility from extracurriculars

Boys & Girls Clubs of America (youth development organization) says to think about how your skills and passions align with the job. A sports team captaincy or a school club role can demonstrate leadership and teamwork.

Practice interview etiquette: firm handshake, eye contact, listening

Soft skills like punctuality, communication, and a firm handshake carry weight. Boys & Girls Clubs of America (youth development) notes that 93% of employers rank soft skills as critical — even for entry-level roles.

Bottom line: The pattern: First-time job seekers face a paradox: you need experience to get hired, but you need to get hired to get experience. The solution is translating non-work activities — school projects, volunteering, hobbies — into professional skills.

Frequently asked questions

What should I bring to an interview?

Bring copies of your resume, a list of references, a pen and notepad, and any work samples if relevant. The Youth Job Center (career readiness nonprofit) recommends preparing these in advance. Also bring a positive attitude and specific questions for the interviewer.

How early should I arrive for an interview?

Aim for 10–15 minutes before the scheduled time. Boys & Girls Clubs of America (youth development organization) recommends at least 15 minutes early for teen interviewees. Any earlier and you might inconvenience the interviewer; any later and you risk appearing careless.

What is the STAR method?

STAR stands for Situation, Task, Action, Result. It’s a structured way to answer behavioral interview questions. Describe the situation you faced, the task you needed to accomplish, the specific actions you took, and the outcome. Understood (learning and attention resources) includes STAR practice as part of preparing teens for interviews.

How do I follow up after an interview?

Send a thank-you email or note within 24 hours. Boys & Girls Clubs of America (youth development organization) recommends this step. Thank the interviewer for their time, reiterate your interest, and mention one specific topic you discussed to jog their memory.

What should I wear to an interview?

Dress slightly more formally than the everyday dress code of the workplace. For most entry-level roles, this means a collared shirt or blouse, clean trousers or a skirt, and closed-toe shoes. The Youth Job Center (career readiness nonprofit) emphasizes not chewing gum as part of professional presentation.

How do I answer ‘what is your biggest weakness’?

Choose a real weakness that doesn’t disqualify you from the role, and explain what you’re doing to improve. For example: “I sometimes get nervous speaking in groups, so I’ve been practicing with classmates to build confidence.” CareerVillage (peer career advice platform) supports being honest while showing willingness to grow.

Is it okay to ask about salary during an interview?

Generally, it’s better to wait until the employer brings up compensation or until you receive an offer. In the first interview, focus on whether the role and company are a good fit for your skills and interests. If the job posting doesn’t list a salary range and you need the information to proceed, ask about the budget for the role politely.
