Many product companies include a round where you design and build a small working system in 60 to 120 minutes: a parking lot, a cab booking service, a library system. Most freshers have never practised it. This article explains what these rounds evaluate, a time-boxed approach from requirements to running code, design principles that matter at this level, a complete small example, typical follow-up questions, and how to practise with AI as a demanding interviewer.

Interviewers in a live coding round are judging how you think as much as whether your code runs. This article describes the technical rounds freshers meet at different kinds of employers, a six-step method for any coding problem, what useful thinking aloud sounds like, how to recover when stuck, how to handle take-home assignments, fundamentals and project deep-dives, and how to practise with AI as a reviewer.

Knowing algorithms is half of an online assessment. The other half is strategy: reading all problems first, using the constraints to tell you the complexity you need, capping time per problem, submitting a working brute force before optimising, collecting partial marks, and testing edge cases before the hidden tests do. Includes a stress-testing technique for practice, with a short program.

Resume advice says to quantify everything, but a student project has no revenue and few users. This article shows which numbers you can legitimately measure (speed, load, correctness, coverage, scale, time saved), how to measure them so they survive questions, how to summarise them with medians and percentiles, and how to turn them into resume bullets with AI without inventing a single figure.

Your own projects show you can build. Outside proof shows that someone else found your work worth accepting, rewarding or reading. This article covers making a first useful open-source contribution in your target stack, entering hackathons for the right reasons, and writing about what you built, with AI as an editor rather than an author.

Turn the tests from the earlier articles into a strategy: unit tests, slice tests (@WebMvcTest, @DataJpaTest, @JsonTest), full integration tests on a real PostgreSQL, measured run times, coverage with JaCoCo, and a mutation experiment that shows which tests really protect you.
