Frequently Asked Questions

Do I need a degree to become a Software Engineer?

No. While a CS degree helps, building a strong portfolio and passing technical interviews is often enough to get hired.

Is AI replacing Software Engineers?

AI is a tool that makes engineers faster, not obsolete. Engineers who learn to use AI (like Copilot) will replace those who don't.

Which programming language should I learn first?

Python or JavaScript are highly recommended due to their readable syntax and massive job demand.

How long does it take to get a job?

If studying full-time, 6-9 months is a realistic timeframe to reach entry-level proficiency.

Do I need to know Math?

Basic logic and algebra are required. Advanced math is only needed for specialized fields like ML or graphics.

What is the difference between a coder and a software engineer?

A coder writes scripts. An engineer designs scalable, maintainable architectures that solve business problems.

Are certifications worth it?

Cloud certifications (AWS/Azure) are highly valued. General coding certificates matter less than actual projects.

How important is LeetCode?

Very important for Big Tech (FAANG). Less important for startups, which prefer take-home projects.

What is an ATS?

An Applicant Tracking System. It's software that scans your resume for keywords before a human ever sees it.

How can I bypass the ATS?

Use a simple format, exact keyword matches from the job description, and quantifiable achievements.

Should I learn frontend or backend first?

Frontend provides immediate visual feedback, making it easier for beginners. Backend teaches deeper architectural concepts.

What is version control?

Tools like Git that track changes to code over time, allowing multiple people to collaborate without overwriting each other.

How many projects should be on my resume?

Quality over quantity. 2-3 highly polished, deployed projects are better than 10 unfinished tutorials.

What is CI/CD?

Continuous Integration and Continuous Deployment. It's the automation of testing and releasing code.

Is a bootcamp better than self-taught?

Bootcamps provide structure and networking, but self-teaching is free. Both require the same amount of personal effort.

How do I practice system design?

Read 'Designing Data-Intensive Applications' and practice drawing architectures on whiteboards.

What is the hardest part of the job?

Reading and understanding legacy code written by someone else years ago.

How do I negotiate my first salary?

Research the market rate on Levels.fyi, get multiple offers if possible, and don't give the first number.

Can I work remotely?

Yes. Software engineering is one of the most remote-friendly professions in the world.

What should I do if I get stuck on a bug?

Read the error message carefully, Google it, ask ChatGPT, or take a walk away from the screen.
