System design interviews are a challenging but important part of the hiring process for software engineers. By practicing common interview questions, reviewing key concepts, and using a systematic approach to design, you can increase your chances of acing a system design interview. Remember to communicate clearly and concisely, and be prepared to explain your design decisions.

If you are studying for an upcoming interview, don't just read the repository passively. Follow this structured approach:

1. Master the Basics (The "Hidden" Requirements) Before designing a system, you must understand the building blocks. The repo covers these extensively:

2. The "RESHA" Framework When tackling a design problem in an interview, follow a structured framework to show your thought process: No verified repo hosts the full PDF legally

3. Case Studies Dive into the "System Design Interview Solutions" section of the repo. Try to solve the problem yourself first, then compare your approach with the provided solution.


Grokking the System Design Interview (Educative.io) is the interactive alternative to PDFs. Many GitHub users share their notes from this course – those notes are legal and verified.

Automatic flight log

All of the flights you performed in the Skylegs Operator Account (via the operations module) sync automatically with your logbook. For this reason, the process becomes much faster for the pilots. Therefore, there is no need to manually log flights, except from flights that are done outside of your main organisation.

Multiple logbooks

Wish Skylegs electronic pilot logbook, you can have multiple logbooks, one for each kind of aircraft. As an illustration, you can have airplane, helicopter, ultralight, glider and drone logbooks. Start them from scratch by entering past flights, or you may choose to import an existing logbook or simply enter your total hours to start tracking future flights.

Flight map & statistics

Visualise where you have been before. See all of the flights you have completed on an interactive map. View your personal statistics on graphics that are grouped by period of time, aircraft type, flight crew function, destination, type of operation and others.

Pilot licenses & exams

Skylegs Pilot Account is not only used for the electronic pilot logbook. You can also enter all of your licenses details, medical examinations, qualifications and ratings. Monitor their expiry dates from a single place.

Paper logbook

Would you like to keep physical copies of your logbook? That is possible. All you need is to download the digital file in Excel or PDF format and print.
