Explore practical, real-world answers designed to help IT professionals grow faster and stay relevant.

Getting Started in an IT Career

Choose a path (IT Support, Developer, BA, Cybersecurity, Cloud, Data).

Learn the basics (computers, networking, databases, a little Python).

Learn skills for your chosen role through online courses.

Get a beginner certification (like ITF+, Google IT Support, AWS Cloud Practitioner, etc.).

Build small projects or a portfolio to show your skills.

Gain experience through internships, freelancing, or volunteering.

Apply for entry-level IT jobs and keep improving your soft skills.

You don’t need a specific degree to start in IT. However, these help:

Best Options (Any One Is Enough):

Bachelor’s degree in IT, Computer Science, or related fields

Diploma or certification course in IT

Online training programs(Coursera, Udemy, Google, AWS)

Self-learning + beginner certifications(CompTIA, Google IT Support, AWS Cloud)

Bottom line:

A degree is helpful but NOT mandatory. Skills, certifications, and hands-on practice matter more.

If you want, I can tell you which education is best for your specific IT role(Developer, BA, Cyber, Cloud, etc.).

Know the interview rounds – practice aptitude (reasoning, math, English), revise basics of programming/SQL/testing, and prepare for HR questions.

Strengthen technical fundamentals – learn data structures, OOP, SQL queries, SDLC/STLC, or basics of your chosen domain.

Practice behavioural questions using the STAR method (Situation, Task, Action, Result).

Prepare your introduction (“Tell me about yourself”), strengths, weaknesses, and project explanations.

Take mock interviews with friends or online platforms to build confidence.

Prepare for online interviews – check your internet, camera, mic, lighting, and background.

Prepare for offline interviews – reach early, carry documents, and maintain good body language.
