2. Required skills highlight karo.
3. Apne resume me matching skills naturally add karo.
4. Project bullets ko role ke hisaab se adjust karo.
5. Summary me role title include karo.

Example agar JD me “RAG, LangChain, Vector Database” hai, toh resume me project bullet me clearly likho.

Step 4: Referral Lo, Sharam Mat Karo

India me referral kaafi kaam karta hai. Cold apply se better referral hota hai.

LinkedIn message template:

“Hi [Name], I saw you work at [Company]. I’m applying for [Role] in Chennai. I have hands-on projects in Python, ML, GenAI and FastAPI, including a RAG chatbot and fraud detection model. If you’re comfortable, could you please refer me? Sharing my resume and job link here. Thanks a lot.”

Step 5: Recruiter Ko Direct Message Karo

Recruiter search karo:

• “Talent Acquisition Chennai AI”
• “Recruiter Machine Learning Chennai”
• “Data Science recruiter Chennai”
• Company name + recruiter

Message:

“Hi [Name], I applied for the AI Engineer role at [Company]. I have experience with Python, SQL, ML, GenAI, RAG, FastAPI and deployed projects on GitHub. Would be grateful if you could review my profile. Here’s the job ID and resume.”

Bas spam mat karna. Polite follow-up 5-7 din baad okay hai.

Step 6: Apply Channels Mix Karo

Best channels:

1. Company career page
2. LinkedIn Jobs
3. Naukri
4. Instahyre
5. Wellfound for startups
6. Cutshort
7. Hirist
8. Referrals
9. Hackathons
10. College alumni network

Naukri profile daily update karo. Ek small change bhi recruiter search me profile ko active dikha sakta hai.

2. Dataset source
3. Data cleaning steps
4. Model selection reason
5. Metrics
6. Errors and limitations
7. Deployment method

Freshers Ke Liye Special Advice#

Agar tu fresher hai aur soch raha hai “experience nahi hai, job kaise milegi?” toh bhai experience ka substitute projects, internships, open-source, freelance, hackathons ho sakte hain.

Do this:

1. 3 strong projects banao.
2. GitHub clean rakho.
3. README professional banao.
4. LinkedIn pe project demo post karo.
5. Kaggle notebooks publish karo.
6. Internship apply karo, paid/unpaid dono initially consider kar sakte ho.
7. College alumni se referral lo.
8. Resume one-page rakho.

Freshers ke liye expected salary Chennai me:

• Service company entry role: ₹3.5 LPA se ₹7 LPA
• Analytics fresher role: ₹5 LPA se ₹10 LPA
• Product company junior AI role: ₹8 LPA se ₹18 LPA
• Strong GenAI portfolio ke saath startup: ₹10 LPA se ₹20 LPA possible

But salary se pehle learning curve dekho. Pehli job me achha project exposure mil gaya toh 2 saal baad jump me ₹18 LPA to ₹30 LPA possible hota hai.

Experienced Candidates Ke Liye Strategy#

Agar tum 2-6 years experience wale ho, toh sirf courses se kaam nahi chalega. Business impact dikhana padega.

Resume me numbers add karo:

• “Reduced manual review time by 35%”
• “Improved model precision from 72% to 84%”
• “Processed 10M+ records using PySpark”
• “Deployed ML API handling 5K requests/day”
• “Reduced cloud inference cost by 22%”

Experienced candidates ke liye Chennai salary:

• 2 years: ₹10 LPA se ₹18 LPA
• 3-4 years: ₹16 LPA se ₹28 LPA
• 5-7 years: ₹25 LPA se ₹45 LPA
• 8+ years AI Lead: ₹45 LPA se ₹80 LPA, product companies me aur zyada

Switch karte time notice period problem hota hai. Agar 90 days notice hai, toh recruiter hesitant ho sakta hai. Negotiate karo, buyout option check karo, early release possibility discuss karo.

Common Mistakes Jo Callback Maar Deti Hain#

Bhai ye mistakes avoid kar, half competition yahi pe out ho jaata hai.

1. Resume me 4 pages bhar dena
   One-page fresher, max two-page experienced.

2. GitHub empty rakhna
   AI role me GitHub blank hai toh trust low hota hai.

3. Sirf certificates add karna
   “Completed AI course” se zyada value project ki hai.

4. JD padhe bina apply karna
   ATS mismatch ho jaata hai.

5. Projects copy-paste karna
   Interview me deep questions aayenge.

6. SQL ignore karna
   Data roles me SQL must hai.

7. Business impact nahi likhna
   Model accuracy alone enough nahi hai.

8. LinkedIn inactive rakhna
   Recruiters LinkedIn check karte hain.

9. Resume file name bad
   “final_resume_new_latest_2.pdf” mat bhejo. Use: “Rahul_Kumar_AI_Engineer_Resume.pdf”

10. ATS formatting kharab
    Tables, graphics, icons, weird columns avoid karo.
