Deloitte — Java Developer
Reported, not verified
These are shared by candidates, not verified by us, and not endorsed or confirmed by the companies named. Everything else on this site is checked on every build; this section is reported rather than verified, and it is kept separate for exactly that reason. Process varies by team, by interviewer and by year, so treat a list as one loop that happened, not as a syllabus you can expect to be repeated.
Source: Interview experience posted publicly on LinkedIn by Vitthal Chandankar (linkedin.com/posts/vitthal-chandankar_deloitte-interviewexperience-javadeveloper-activity-7369635364019273730-loqP). Reproduced as posted; not confirmed by Deloitte. The post carries no reliable date, so none is claimed here. Two of the ten questions are described in the post rather than quoted, and are paraphrased below. Other pages ranking for this company were topic lists written by preparation sites with no candidate sourcing at all, and are not used.
0 of 10 of these have a deep-dive answer on this site. The rest are not covered yet and are marked so — a gap you can see is more useful than one you cannot.

What this list is worth
One loop, one team, one day. It is calibration, not a syllabus — useful for the shape and depth expected at 3–5 years, not as a prediction of what you will be asked. For patterns across many interviews rather than a single list, the company-type breakdowns are the better guide.
Every other page on this site compiles and runs its code on each deploy and diffs the output against what the page claims. This page cannot work that way — it reports what someone else said — so it is kept in its own section and labelled on every view.
