The IT Roles Field Guide (FREE) with Raghu Datta

Job titles in IT sound alike from outside. Inside, the days are very different: one person cleans a spreadsheet all morning, another calms a worried user on a call, another watches a server graph. This free guide shows seven entry roles from the inside, so you can pick one with open eyes and start learning it this week.

Inside: data analyst, business analyst, UI/UX designer, cloud support engineer, technical support engineer (L1 and L2), DevOps engineer, and the tech roles where a BCom degree is a plus. For each role: a normal day, the skills in order, a four-week learning path using only free courses (Kaggle Learn, Microsoft Learn, AWS Skill Builder, Cisco Networking Academy, GitHub Docs and more), a starter project with a checklist, and interview questions with how to answer. Plus all seven roles compared on one page, a ten-question self-check that points to your best fit, 15 copy-paste AI prompts, a four-week practice plan and a printable checklist.

Free, 52 pages, phone friendly, drawn illustrations throughout.

What you'll learn:

Seven roles, from the inside: Data analyst, business analyst, UI/UX designer, cloud support, technical support, DevOps and finance-plus-tech: what a normal day actually looks like in each.

Four free weeks per role: The skills in the order to learn them, each week tied to a free course or official guide, with the source listed.

A starter project for each: A dashboard, a user-story spec, a screen redesign, troubleshooting notes, a mock ticket pack, a first pipeline, a spends report: the thing you show in interviews.

Interview questions with answers: Real questions for each role, with how to answer them in a sentence or two.

Which role fits you: All seven roles on one page, and a ten-statement self-check that points you to one or two.

15 AI prompts: Explore a role, learn a skill step by step, plan your project, run a mock interview, practise a support call. Every prompt teaches or checks; none does the work for you.

FAQs:

Do I need a computer science degree?

No. The guide covers roles that BSc, BCA, BCom, BBA and other graduates start in, and chapter 07 is written for commerce students.

Are the courses really free?

Yes. Every course in the four-week paths is free, and each one is listed in the Sources section so you can check it.

Does it list salaries?

No. Pay changes by city and company, so the guide points you to current job postings instead of printing a number.

Which AI tool do I need?

Any chat assistant works: ChatGPT, Gemini, Claude, Copilot or another. The free versions are enough.
