He will ask you to run the project in two different browsers... One for admin another one is for user

Times asked 1
Official solution

SimpleMAD2 orchestra: Redis, Flask, Vue, worker, beat — 5 terminals.
Ports: Flask 5000, Vite 8080/5173, Redis 6379. CORS isliye.
Order: Redis first. Worker bina Redis fail. Beat bina worker queue bharti.
Pehle 1-line definition, phir related MAD2 layer (Vue SFC / Flask route / models.py / tasks.py / Redis).
4-line formula: input kahan se aaya, auth/validation kaunsa, DB ya cache ya Celery, kya return.
Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.
Example
```
redis-server
flask run --port 5000
npm run serve
celery -A app.celery worker -l info
celery -A app.celery beat -l info
```
Project example: README local_run. Dikhao 5 processes + browser two roles.
Viva tipPorts batao: Flask 5000, Vite 8080/5173, Redis 6379. CORS isi liye chahiye.

If a parking lot has multiple floor for parking, how will you add that information in models, what will be more efficient new table for floor or add floor information in parking_lot table He will ask questions based on the project flaws....like if anything can be improved,how can you improve that( he will ask the logic, and ask you to implement it sometimes)

Times asked 1

Official solution

SimpleImprove ideas: caching, better validation, tests, pagination, email reminders, accessibility, mobile UI, logging.
Viva tip1-2 concrete features bolo jo time milne pe add karte — vague 'AI' mat.

Advice: He is a nice proctor. He explains if you don't able to answer. Viva was like two techy guys discussing the project. I also asked him how my viva went. He told me my viva was nice, Though I couldn't answer 2-3 questions. He also allowed me to explain things in Hindi. When I asked him how was my viva... He told me to improve my English bcoz in industry you have to speak in Hindi. It will not affect your viva but you need to be confident about this. Otherwise your viva was pretty much okay.
