I recently attended an interview with Deloitte US, and I’m sharing my experience so it can help others preparing for the same. The whole selection journey had six rounds: one written test, two technical interviews, one English test, one director-level discussion, and finally an HR round.
The written assessment was conducted through Cocubes. It had 30 MCQs to solve in 30 minutes, all based on technical topics. Some of the “predict the output” programs had intentional compilation errors, so you must read each question very carefully before choosing an answer.
The next stage was a face-to-face technical round. I was asked questions like:
• What is multithreading in Java?
• How does a deadlock happen?
• How can you break a deadlock?
• What does the volatile keyword do?
• Which J2EE feature do you prefer and why?
• Different ways to create threads in Java and details of thread-related methods.
They also pick questions directly from the skills mentioned in your resume, so it’s better not to add anything you’re unsure about.
The third technical round was another F2F interview, mainly focused on coding. I was given a table with columns like EMPID, EMPNAME, DEPTID, SAL, and I had to find the 6th highest salary in each department. I first solved it using Java, and then they asked for the SQL version.
There was another scenario: one REST service only accepts data wrapped in double quotes (" "), but the provider service sends numbers without quotes. I had to explain how to wrap the numeric values before forwarding them. More questions followed on:
• Different types of sorting
• Difference between ArrayList, Vector, and LinkedList
• A few HR-style questions like weak points, suggestions to your supervisor, etc.
The fourth stage was an English test by Versant. Their website has sample content, so practicing those helps a lot.
Next was the director round. A senior manager interacted with me and spoke about project responsibilities, work culture, and expectations. Questions included things like “Why do you want to leave your current company?”, “What interests you about Deloitte?”, and “Are you comfortable with shift timings?”
The final stage was the salary discussion. Once that was done, the process came to an end.
Interview tips shared by Ananya Deshmukh:
• Be confident and calm.
• Never add anything fake in your CV.
• Try to make the conversation comfortable for both sides.
• Remember, you are exploring a better opportunity, so don’t panic.
• Revise SQL before appearing.
Thank you, and wish you all the best for your preparation.
