Placement Season Starts in 30 Days. Here's the Maximum-ROI Last-Minute Preparation Plan.
Your placement season starts in 30 days. You know you should have started preparing in 5th semester. You did not. You now have one month and a rising sense of panic. Every placement preparation guide you read assumes you have 6-12 months. This guide assumes you have 30 days and need a triage plan — maximum placement ROI per hour of preparation. Some things are worth doing in 30 days. Some things are not. Here is which is which.
THE 30-DAY TRIAGE: WHAT TO STUDY AND WHAT TO SKIP
| ACTIVITY | DOES IT HELP IN 30 DAYS? | WHY / WHY NOT |
|---|---|---|
| Learning a new programming language | No — too late | Language fluency takes months. Interview in whatever language you already know. Do not start Java if you only know Python. Do not start Python if you only know C. |
| Building a new full-stack project | Yes — deploy a minimal but complete one in 5 days | Not a polished project. A small, deployed, documented project with a live URL. The URL is the signal. The project itself can be basic. |
| Solving LeetCode problems | Yes — focus on top 50 patterns | Do not aim for 200 problems. Aim for 50 problems covering arrays, strings, linked lists, stacks, and hashing. These 5 topics appear in every company’s coding round. |
| Learning system design from scratch | No — takes months | System design interviews are for experienced roles. Fresher system design is rare. If asked, you will be asked to design a URL shortener or a rate limiter. Read one article on each. Move on. |
| DBMS / OS / CN theory revision | Yes — 3-4 days of focused revision | Service companies test these subjects. Revise the top 50 interview questions per subject from GeeksforGeeks. Do not read the textbook. Read the questions and answers. |
| Writing a new resume | Yes — 2 days | Delete the objective. Delete 15 of the 20 skills you listed. Add your GitHub link. Add your deployed project URL. Add open source PR if you have one. Proofread. Done. |
| Watching online courses / tutorials | No — zero time for passive learning | Every hour you spend watching a video is an hour not spent writing code or solving problems. Passive learning has a 30-day ROI of zero. Do not do it. |
Research each company the night before they visit. What is their business? What stack do they use? What do they test in interviews? Prepare 3 questions to ask the interviewer. "What does a typical first project look like for a new joiner on your team?" "What does your code review process look like?" "What do you wish you had known when you started at this company?" These questions signal genuine interest. Re-read your own resume before each interview. If the interviewer asks about a project you listed and you cannot explain the architecture in 60 seconds, you lose credibility. After each rejection, take 2 hours. Then reset. Do not check the WhatsApp group. Do not compare offers with friends. Do not calculate how many companies are left. Focus on the next interview. Placement season is a marathon. The candidate who stays composed across 10 rejections and performs on the 11th is the one who gets placed.
