The first round is an elimination round with an MCQ test. It has 3 sections: Aptitude, Operating Systems, and Computer Networks in the first section, C/C++ Technical Questions in the second, and DBMS and SQL Questions in the third. Candidates who passed were called for the second round the next day. The second round had 3 technical interviews and 1 HR interview. Practicing SQL queries is a must.

The second interview was a market sizing question about how many swipes happen in the NYC subway in a day, and the interviewer helps you with the answer.
- Can you tell me about yourself?
- What are the features/type of population in the airline industry?

Opera Solutions recruited from our college during the campus placements. The first step was resume screening. Next, we had a 60-minute aptitude and logical reasoning test. After that, shortlisted candidates went through three interviews. The first interview was a mix of technical questions and guesstimates, with some unexpected questions to test stress handling. This was an elimination round. The second interview was a brief HR session, not an elimination round. The final interview covered technical, HR, and other aspects. It felt like they had already decided who to hire and weren't very open to hiring many people, rejecting candidates for odd reasons even after good interviews.
- There were riddles and some math problems, such as divisibility tests, to assess aptitude.
- Also, there were guesstimate questions, for instance, estimating the number of barbers in Noida.
Solutions Analyst
First, you'll need to do some reading up on the company and their main product, the Signal Hub platform. You don't have to be an expert on Signal Hub, but get the basics down and also read up on the big data industry and how it's changed over time. Opera's blog about the big data industry is a good place to start. Next, come up with at least 5 questions to ask your interviewers. Then, be ready to talk about your resume in detail because they'll ask you questions about it. Just be yourself during the interview, and don't stress out. Finally, have a clear reason why you want to be in the big data industry and what specifically attracts you to Opera.
- What makes you want to work in the big data industry and what is it about Opera that appeals to you?
