I applied through university. I interviewed at WSO2 (Colombo, Western) in Jan 2026
Interview
It has 6 rounds of interviews where 4 of them are technical interviews and others are HR related. Overall there is a standardized process of hiring for anyone. First two interviews mostly focus on basic concepts and the projects that we have done. 3rd interviews mostly focus on getting an in deep idea about our understanding on work being done in projects.
2 technical interviews, 2 semi-technicals and a friendly discussion with HR and CEO. Overall looking at DSA solutions, Java, concurrency and OOP concepts. Might ask about past projects or ongoing projects if listed in the resume.
