The technical interview, prepared for deliberately: data structures and algorithms by pattern, problems in a sensible order, system design and behavioural rounds.
Finish this and you can solve medium problems in under thirty minutes while explaining your reasoning, and tell your own stories with evidence.
If you never took the course, take it now: the ideas every problem set assumes.
Two pointers, sliding windows, graphs, dynamic programming: learn the pattern, then the problems that use it.
Build this
Practice that compounds.
Done when: The log, with your solve time trending down.
Résumés, recruiter screens, the rounds, the offer: what happens and how to prepare for each step.
For mid-level and above: a structured approach to designing a large system out loud.
Stories with evidence: what you did, what changed, and what you learned.
Build this
Write eight stories from your own work: a conflict, a failure, a decision with little data, leading without authority, and four of your best results. Each in STAR form with a number in the result. Then practise them out loud in CareerOS Interview practice and keep the scores.
Done when: Eight written stories and your practice scores.
