Avito’s 2026 engineering loop: HR screen, Go and distributed systems, practical algorithms, listing-search system design, and a final culture round. A two-week plan plus mock interviews and quizzes on the gym.
A Go theory cheat sheet: goroutines vs threads, buffered channels, the G-M-P scheduler, concurrent GC, slices vs arrays, maps, strings, interfaces, defer, data races, context, and runtime init. Tables, pitfalls, 30-second answers.
A 2026 career comparison: Data Engineer vs Data Scientist across work, stack, salaries, degrees, specializations, and market growth. Tables, workflows, a decision framework — then practice the answer on a mock.
The six theory prompts that show up beside coding tasks: sorting families, graph shortest paths, dynamic arrays vs lists, balanced BSTs, complete trees, and hash collisions. Trade-offs, follow-ups, and a complexity cheat sheet.

A 2026 prep map: what changed, real prompt families, a five-step 45-minute loop, week plans — then timed quizzes and a pair mock so the list is not memorization.
Some loops hand you an assistant, others disqualify you for opening one. Which companies do what, how the AI-enabled round is scored, and a drill for both.
A 2026 reading list for system design interviews: Kleppmann, Xu, Newman, Huyen — then quizzes, a pair mock, and Gym courses so the books do not stay theory.
