Interviewing at Opera Solutions
You should expect a consulting-style process that mixes case work and quantitative evaluation with technical screens. The extracted topic data shows Excel, SQL, mathematics, quantitative aptitude, estimation and guesswork, logical reasoning, and data structures all show up prominently, alongside consulting case study analysis and case interviews.
What they test most consistently is your ability to solve structured problems under pressure. Across the topics, Excel (including VLOOKUP) and SQL (including SQL JOINs) are central, and the data structures and logical reasoning topics are also top-tier. For machine learning oriented roles, there is strong coverage of machine learning fundamentals, model knowledge, and problem solving under constraints.
From the process steps, you can expect both screenings and multiple interview rounds that include case analysis, case studies, and in-person or face-to-face interviews, plus at least one HR or behavioral conversation. However, the candidate reports provided show an offer rate of 0.0%, so you should treat this as a strict filter process rather than something where most loops end in offers.
Excel and SQL are not side topics here, they are at the same prominence level as the core technical screening areas, including VLOOKUP and SQL JOINs, so you should prepare those specifically rather than relying only on general analytics or coding practice.

The interview process, end to end
5 rounds · based on 125 candidate reports- 1Initial Screening
You will be screened based on your resume with a brief conversation about your background. Some roles also include a phone screen that combines behavioral and technical questions, so be ready to answer both fit and fundamentals quickly.
- 2Behavioral and HR Conversations
You should expect behavioral evaluation or a behavioral interview focusing on past experience and work style, plus an HR interview about motivations, career aspirations, and alignment with company values. Prepare specific examples that map to collaboration and decision making.
- 3Case Analysis and Case Studies
You will tackle real-world business scenarios and case analysis, with emphasis on oral presentations and being able to discuss your thought process and findings. Topic data indicates case interviews and consulting case study analysis are highly prominent, so practice structuring your approach out loud.
- 4Technical Assessments, Including Paper Test and In-Person Rounds
Some roles include a paper test that evaluates mathematical aptitude, reading comprehension, and case-solving capabilities. Other roles include face-to-face or in-person interviews with additional behavioral assessments and multiple rounds with different stakeholders, so expect follow-ups that test both reasoning and technical skills.
- 5Panel and Multiple Stakeholder Rounds
For some roles, you will meet multiple stakeholders in series, including roles like department heads and sales executives. There can also be multiple rounds overall, so be ready to revisit your thinking, maintain consistent reasoning, and handle questions from different perspectives.

What separates offers from rejections
Patterns from candidates who got offers, and the mistakes that most often sink a loop.
Do this
- Practice consulting-style case interviews and case studies with clear oral structure. The process explicitly includes case analysis with discussion of thought process and findings, and the topic data shows case interview prominence.
- Rehearse SQL JOINs and end-to-end query reasoning, including how joins affect results. SQL and SQL JOINs are both at the highest prominence in the extracted topics.
- Prepare Excel tasks that go beyond formulas, especially VLOOKUP. Excel has the top prominence, and VLOOKUP is also highly prominent.
- Train your quantitative reasoning for both estimation and quantitative aptitude. The topics include estimation and guesswork reasoning and quantitative aptitude with very high prominence.
Avoid this
- Do not assume you can skip Excel or SQL in favor of general problem solving. The topic data places Excel, SQL, and SQL JOINs at the highest prominence levels.
- Do not under-prepare for math and structured reasoning. Mathematics and quantitative aptitude are top prominent topics, and logical reasoning and data structures are also heavily represented.
- Do not treat machine learning questions as optional if you are interviewing for ML related roles. Machine learning fundamentals, model knowledge, and problem solving under constraints are all highly prominent in the topic set.
- Do not go in expecting offers will be common based on your peers. The candidate reports you have show an offer rate of 0.0%, so the bar appears very high.
Opera Solutions interview FAQ
Answered from real candidate and workplace dataWhat does the screening look like?
There are multiple screenings reported across roles, including an initial screening focused on your resume and a phone screen that mixes behavioral and technical questions. Plan to be able to discuss your background briefly and then handle some technical and reasoning questions early.
How difficult are the interviews?
Candidate-reported difficulty is mostly medium at 65.5%, with hard at 23.5% and easy at 9.2%. Very hard is 1.7%, so you should be ready for a meaningful fraction of challenging rounds.
Which topics should I prioritize most?
The highest prominence topics are Excel, SQL, mathematics, case interviews, consulting case study analysis, and machine learning fundamentals, plus data structures and logical reasoning are also very prominent. There is also strong coverage of quantitative aptitude, estimation and guesswork reasoning, SQL JOINs, and VLOOKUP.
How long is the process and how many rounds should I expect?
The process includes initial screening, case analysis or case studies, HR or behavioral interviews, and multiple rounds with different stakeholders, including face-to-face or in-person interviews and panel interviews in some roles. The data does not provide durations, so you should prepare for several stages but cannot rely on a specific timeline.
Do candidates get offers from these loops?
In the provided candidate reports, the offer rate is 0.0%. That means you should assume the process is highly selective and focus on maximizing performance at every stage.
What are candidates commonly positive or negative about?
The reported positive sentiment is 57.6%, so more than half of the feedback is sentimentally positive. The dataset does not break this down by specific stage, so you cannot infer which step drives positivity or negativity.
