Optimizing Room Booking Software Architecture: Seeking Solutions for Streamlining Operations
Discussion
I am currently developing a room booking software. The backend is implemented in Spring Boot, and the frontend is written in TypeScript. Communication between components is done through a REST API. Currently, there are various endpoints, including the locations endpoints (building, room, workplace) and the booking endpoints (Single-Booking and Work Model). We refer to Single-Booking for ad-hoc bookings, while the Work Model deals with recurring bookings. When making a booking, the endpoint always expects a room ID. A challenge arises when trying to create an overview of which rooms are occupied at a specific time. Currently, I retrieve workplace data for a room in the frontend, then query the booking endpoint for current bookings, and calculate occupancy from there. However, this approach requires multiple requests and results in complex logic in the frontend. I am now considering whether to expand or modify the backend to address this. I've also received advice to handle bookings entirely through the Workplace endpoint, as booking is seen as a state and not a standalone object. However, I am still uncertain whether this is the best solution. I would appreciate suggestions on how to structure this system for optimization

Booking Interview Process Overview
The Booking interview process typically includes a recruiter screen, one to two technical phone screens, and a 4-6 round on-site or virtual on-site loop. Each round serves a distinct calibration purpose: coding rounds measure correctness, code quality, and complexity reasoning; system design rounds measure architectural judgment at the appropriate level; behavioral rounds measure ownership, leadership scope, and collaboration. Reports tagged on LeakCode from 2024-2026 show Booking runs a calibrated process consistent with industry norms for companies of its tier.
Difficulty calibration: Booking coding rounds typically run medium difficulty with follow-up depth as the senior discriminator. System design rounds expect production-grade trade-off articulation at L4+ levels. Behavioral rounds expect quantified outcomes ("reduced p99 latency from 800ms to 120ms") rather than vague impact claims. The candidates who advance consistently demonstrate clear thinking out loud rather than perfect final answers.
How To Use Booking Question Reports
Real candidate-reported interview questions are a calibration tool, not a memorization target. Booking updates its question pool every 2-4 months; memorizing exact problems risks misleading you when the interviewer uses a variant. The high-leverage approach: identify the patterns that appear repeatedly in Booking reports, practice those patterns on similar (not identical) problems, and use the reports to understand the interviewer's typical follow-up depth.
Filter the questions above by round type, difficulty, and recency. Focus first on reports from the past 6-12 months; older reports may reference questions that have since rotated out of Booking's pool. Reports tagged with quantified difficulty and explicit round type are higher-signal than reports without those tags. The metadata filters help you build a focused study plan in 1-2 hours rather than 8-10 hours of unstructured browsing.
Common Booking Interview Mistakes
Reports tagged "no hire" at Booking consistently surface a few patterns: jumping into code without clarifying requirements, coding silently for extended periods, missing edge cases (empty input, single element, large input, overflow), producing working code the candidate cannot refactor when probed, and behavioral stories that use "we" instead of "I" diluting individual signal. Strong candidates explicitly avoid these patterns by following a consistent round template.
The single most predictive failure mode in recent reports: not asking clarifying questions. Interviewers are explicitly trained to weight this dimension. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into implementation immediately. Strong candidates also verbalize their approach before writing code; weak candidates code in silence and lose the communication dimension of the round's calibration.
