You could even tell us about one thing or two you created that you are particularly proud of or the most challenging features you’ve worked on.
Before the interview we would like you to build a project which might be somewhat similar to your everyday work at BookingSync. The project should consist of two applications:
Mini-BookingSync API
Generate a new Rails application and build REST JSON API with 2 endpoints: Rentals and Bookings with full CRUD. Rental is something that you can book for a particular period of time (like a vacation villa or a hotel) and Booking is a reservation for given Rental for a particular period of time.
The API should be authenticatable by a token (can be one global hardcoded token, no need for refresh token, expiring tokens etc. this time, keep this part simple).
Rentals should have :name attribute, daily_rate attribute and should have many bookings. Bookings should have start_at and end_at datetime attributes which indicate the time period of the reservation, client_email attribute, just to know for whom it is supposed to be and :price attribute, which will be the price for this booking.
Price calculation for the booking should be simple: only daily_rate should be considered when calculating the price. If the rental’s daily price is equal to 100, the booking’s price for 3 days should be equal to 300, for 5 days it should be 500 etc.
All attributes for both Rentals and Bookings should be required. Make sure that:
- the dates for bookings don’t overlap
- the price for given period is valid when creating a booking
- the reservation should be possible for at least one night / day stay
Mini-BookingSync API Client
Generate a new Ember application that would serve as a client of the Mini-BookingSync API. This application should be able to handle all CRUD actions for both Rentals and Bookings endpoints. The essential part of the application would be creating bookings for given rental - a user should be able to pick start at and end at dates, fill in client email, see the price for given period of time and create a booking.
Treat this assignment it as if you were building a real-world application. If you think some other validations or requirements would make sense from the domain perspective, feel free to add some extra things.
Don’t forget to include a GitHub repository URL(s) in your email. Good luck and see you at the interview!
