What comes up
Recurring themes from candidate accounts, not a question bank. Nobody is served by leaked question lists, least of all you in the interview.
Deep dive on a recent project
OfficialExpect detailed questions on a project you worked on recently, including the technical challenges and the decisions you made.
Distributed systems design
OfficialDesigning a scalable, reliable and fault tolerant system, ideally with technologies you already know well rather than fashionable ones.
Collaboration and delivery
OfficialBehavioural questions on working in a team, communicating, delivering complex projects and separating your own contribution from the team’s.
Impact and leadership (Senior Staff+)
OfficialSenior Staff+ candidates have an extra stage on how they proactively spotted problems or opportunities and influenced stakeholders.

A bundle of five company-specific question courses covering the problems most often reported from Meta, Microsoft, Amazon, Google and Oracle coding rounds, each split into easy, medium and hard sets with worked solutions. It suits candidates who already know the core patterns and have a loop booked at one of these companies, and want to rehearse on the questions those interviewers are known to ask.

The second volume of Grokking the System Design Interview, aimed at senior and staff (L5/L6) design rounds. It works through harder case studies such as a payment system, flash sale, notification service, unique ID generator, Gmail, Reddit, Google Calendar and a code judging system, then goes beneath them with patterns like quorum, write-ahead logs and vector clocks and deep dives into Dynamo, Cassandra, Kafka, Chubby, HDFS, GFS and BigTable.

The quick-revision companion to the University to job-ready roadmap: OOP, Git and engineering practice, data structures, DBMS, operating systems and networks, then projects, choosing a direction, getting experience and the hiring process. It has editions for first or second year, third year, and final year. Revise a chapter a week alongside your courses and before assessments.

What it pays
Nothing collected for this company yet, and nothing worth guessing at. A made-up range is worse than no range because people negotiate against it.
What they build on
Universities they recruit from
No sourced university links yet. A campus drive, a career fair appearance or an internship partnership is what puts a university here.
How to actually get seen
Refresh your memory of a recent project in detail before the initial call. If you take the home task, write in a language you know well and include a README that explains your structure and trade-offs.

Stuck on something specific?
Writing only gets you so far. If you want an answer to your situation rather than the general case, book a session and we will work through it together. Sessions are free for approved Sefism members, and a few slots open each week.
