Resume & ATS Career & HR Interview Guide · Resume & ATS

Short answer: An ATS-friendly resume is simple, keyword-aligned, and evidence-based. Use plain formatting so systems can parse sections correctly, then make each bullet prove measurable impact. If ATS can read it and a recruiter can scan it in 20 seconds, you are on the right track.

Step-by-step approach

  1. Use a single-column layout with standard headings like Summary, Skills, Experience, and Projects.
  2. Extract required keywords from JD and incorporate them naturally in skills and bullets.
  3. Rewrite every bullet as Action + Context + Result with numbers where possible.
  4. Remove tables, icons, and text boxes that often break ATS parsing.
  5. Keep file as PDF or DOCX only if the job portal specifically supports it.
  6. Run a final ATS score check and human readability review before applying.

Real-world example

Priya applied to 40 roles from TCS and got almost no callbacks. Rahul from Razorpay reviewed her resume and found heavy design formatting with missing backend keywords. She rebuilt it into a clean one-column format with impact metrics for latency and uptime improvements. Callback rate improved within two weeks.

Mistakes to avoid

  • Using visually rich templates that ATS cannot parse properly.
  • Stuffing keywords unnaturally and reducing readability.
  • Listing responsibilities without measurable outcomes.
  • Submitting same resume to all roles without adaptation.

Resume & ATS Career & HR Interview Guide · Resume & ATS

Short answer: A professional summary should state role identity, core strengths, and business impact in 3 to 4 lines. It is not an objective statement or motivational quote. Think of it as your positioning headline for recruiter skimming.

Step-by-step approach

  1. Start with your role + years of experience + core domain in one sentence.
  2. Add 2 key strengths aligned to target job requirements.
  3. Include one measurable achievement that supports credibility.
  4. Mention preferred scope, for example product backend or ML platform work.
  5. Keep total length under 70 words for readability.
  6. Customize summary slightly for each major role type you apply to.

Real-world example

Karthik’s resume opened with a vague line: "Seeking challenging opportunities." Isha from PhonePe helped him rewrite the summary to mention backend expertise, payment-domain experience, and latency improvement outcomes. Recruiters could now understand his profile in seconds. He started receiving more relevant interview calls.

Mistakes to avoid

  • Using generic objective lines with no role signal.
  • Writing a 150-word paragraph that no recruiter reads.
  • Adding personal adjectives without proof.
  • Forgetting to align summary with target job type.
Your summary should answer: who are you, what can you deliver?

Short answer: No-experience resumes should highlight projects, internships, coursework relevance, and problem-solving evidence. Recruiters know you are entry-level; they want proof that you can execute and learn quickly. A focused project-first resume can outperform a generic fresher template.

Step-by-step approach

  1. Open with a clear summary of target role and relevant technical stack.
  2. Prioritize academic or personal projects with measurable outcomes.
  3. Add internships, hackathons, open-source work, or freelancing if available.
  4. Keep skills limited to tools you can explain confidently in interviews.
  5. Include links to GitHub, portfolio, and deployed demos.
  6. Tailor project keywords to each role before applying.

Real-world example

Ananya was a fresher from Hyderabad with no full-time work history. Vikram from Infosys helped her place projects above education and add measurable outcomes for each build. She added GitHub links and one deployed app demo in her resume header. Her profile started receiving internship-to-full-time callbacks.

Mistakes to avoid

  • Leaving project section vague with no outcomes.
  • Adding every class assignment as if it were production work.
  • Listing advanced skills without practical proof.
  • Ignoring portfolio links in resume.
For freshers, projects are your experience.

Short answer: Tailoring means changing emphasis, not inventing experience. Mirror the job language, prioritize relevant achievements, and remove distracting content. A targeted resume dramatically improves ATS match and recruiter response rate.

Step-by-step approach

  1. Read JD carefully and mark required skills, domain context, and responsibility keywords.
  2. Reorder experience bullets so most relevant impact appears first.
  3. Swap project examples to match target role expectations.
  4. Adjust summary line to reflect role title and domain focus.
  5. Update skills section to emphasize directly relevant tools.
  6. Run a quick ATS keyword-gap check before submitting.

Real-world example

Meera used one generic resume for all roles while applying from Infosys. Rohit from Freshworks showed her how to create two versions: backend-heavy and data-heavy. She reordered bullets and projects based on each JD instead of rewriting from scratch. Her interviews became more relevant and conversion improved.

Mistakes to avoid

  • Copy-pasting JD words without matching evidence.
  • Changing everything and losing profile authenticity.
  • Keeping irrelevant projects at top due to personal preference.
  • Sending same resume to fundamentally different role types.
