ABC Education Software Engineer interview: OS, DBMS, OOP, and DSA

I started with an online assessment that combined coding with multiple-choice questions in OS, DBMS, OOP, SQL, and aptitude. Soon after, the first technical round covered my resume and projects, then DSA and broader computer-science fundamentals. I spent most of it explaining my reasoning rather than only stating answers.

The next technical round was harder: a deeper coding problem, project follow-ups, and basic system design. I was expected to connect how a feature worked with its tradeoffs. The final HR and hiring-manager discussion turned to communication, teamwork, career goals, and cultural fit.

It was coding intensive, with a strong emphasis on DSA and core CS. The interviews tested whether I could explain my projects confidently. The experience was smooth and professional, but it was neither quick nor low pressure.

Location: Korea. Overall feedback: neutral. Offer status: no offer.
