-> download file from portal, demo - of specific features he requests

Times asked 1

Official solution

SimpleExaminer portal wala submitted ZIP chahta hai. Local extra changes mat dikhana.
Suggested flow1) Portal ZIP download
2) Extract
3) venv + pip install -r requirements.txt
4) flask run / python app.py
2
-> app.py & routes - specific line explanations (whichever he requests)

Times asked 1
Official solution

SimplePehle 1-line definition, phir apne MAD1 project mein file dikhao, phir chhota example.
Suggested flow1) Concept kya hai?
2) Mere code mein kahan?
3) Example / demo
4) Edge case
Example
```
# related file: models.py / routes / template
# formula: request → check/auth → DB → render/redirect
```
Viva tipExact line yaad nahi to honestly related part dikhao. Bluff mat karo.
3
-> model.py - Backref meaning, how it's defined in python

Times asked 1
Official solution

Simplebackref reverse attribute auto banata hai. back_populates dono sides explicitly naam dete ho — clearer.
Example
```
# backref
spots = db.relationship('Spot', backref='lot')
# spot.lot available

# back_populates
spots = db.relationship('Spot', back_populates='lot')
# Spot.lot = db.relationship('Lot', back_populates='spots')
```
4

-> How do you implement upload an image and store in the app

Times asked 1

Official solution

SimpleCode explain formula: input kya aaya → auth/validation → DB change → response/UI.
Viva tipFunction signature + 3-4 important lines + edge case.
5
-> Put vs patch

Times asked 1
Official solution

SimplePOST naya janam (har baar naya id). PUT poori photo replace. PATCH sticker chipkao.
POST create, not idempotent. PUT full update, idempotent. PATCH partial.
POST ki jagah PUT se REST semantics toot. GET typically no body.
CRUD map: POST create, GET read, PUT/PATCH update, DELETE delete.
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
```
POST /api/venues
PUT  /api/venues/1   {all fields}
PATCH /api/venues/1 {only name}
```
Project example: POST /api/venues create. PUT /venues/1 saari fields. PATCH sirf name.
6

-> Specific feature demo, like Unassign a trek from staff.

Times asked 1

Official solution

SimpleDemo script pehle se practice: 5–7 min, Admin + User roles, saare mandatory features.
Suggested flow1) Register/login user
2) Admin login — CRUD
3) Approval/blacklist
4) Booking/apply + edge case
5) Search
6) Logout
Viva tipBolte-bolte dikhao. Code tab kholna jab poochhein.
7

Times asked 1

Official solution

SimpleProject overview: problem → roles → main entities → key flows (register, book, admin approve).
Viva tip1 minute elevator pitch ready rakho, phir demo.

Advice: He is great, He tests if you know what you wrote. Be confident and explain what you know, accept that some little things you maybe wrong, so you'll look over it. He appreciates logic.

* Focus more on the Celery tasks. Be ready to make time changes or work on the email export functionality.

Times asked 1
Official solution

SimpleLive UI change: relevant CSS/HTML template kholo — color, margin, flex, bootstrap class. Save + hard refresh.
Example
```
/* button red */
.btn-primary { background: red; }

/* center navbar item */
.navbar { justify-content: center; }
```
Viva tipDevTools se pehle try, phir file mein permanent change.
4

* Coding question: Write a simple Celery task. Know both how to send it with `.delay()` and how to retrieve the result. Also know how to connect it with APIs.

Times asked 1

Official solution

SimpleLive coding: notepad/editor mein chhota Flask route / Jinja loop / model field. Calm raho, run karke dikhao.
5
* What does `fetch()` do?

Times asked 1

# related file: models.py / routes / template
# formula: request → check/auth → DB → render/redirect
```
Viva tipExact line yaad nahi to honestly related part dikhao. Bluff mat karo.
6
* What is `localStorage` vs `sessionStorage`?

Times asked 1
Official solution

SimplelocalStorage browser mein key-value string store karta hai — tab band hone pe bhi rehta hai. Token/theme ke liye use.
Example
```
localStorage.setItem('token', jwt)
const t = localStorage.getItem('token')
localStorage.removeItem('token')
```
Viva tipSensitive password mat rakho. XSS se steal ho sakta hai — HttpOnly cookie safer for session.
7
* How have you implemented authentication? How do RBAC and the JWT decorator work?

Times asked 1
Official solution

Simplelogin_required jaisa decorator protected routes pe: session nahi to login redirect.
Example
```
def login_required(fn):
    @wraps(fn)
    def wrapper(*a, **k):
        if 'user_id' not in session:
            return redirect(url_for('auth.login'))
        return fn(*a, **k)
    return wrapper
```

Advice: Keep it quick. Don't delay. He is not rude, but he's really not lenient. He will score you a little on the tougher side, so answer to the point. Don't shy away from asking for clarification before answering the question. I messed up on that. But yeah, the main focus is your code. He is more focused on the backend.

theory : what is backref vs backpopulation

Times asked 1
Official solution

Simplebackref reverse attribute auto banata hai. back_populates dono sides explicitly naam dete ho — clearer.
Example
```
# backref
spots = db.relationship('Spot', backref='lot')
# spot.lot available

# back_populates
spots = db.relationship('Spot', back_populates='lot')
# Spot.lot = db.relationship('Lot', back_populates='spots')
```
10
what is cors

Times asked 1
Official solution

SimpleDifferent origin Vue vs Flask — browser CORS check. Server Allow-Origin.
Failed = frontend error even if curl works. Examiner curl vs browser.
HTTP verbs + status REST ki zabaan. GET read, POST create, PUT replace, PATCH partial, DELETE remove. GET typically no body.
Status: 200 OK, 201 created, 202 accepted (Celery task), 400 bad input, 401 no/bad token, 403 role nahi, 404 missing, 409 conflict (double book), 500 server.
AJAX/fetch page reload nahi. SPA poori isi pe. Postman se bina Vue ke API prove karo — examiner pasand.
Example
```
from flask_cors import CORS
CORS(app, resources={r'/api/*': {'origins': 'http://localhost:8080'}})
```
Project example: Flask-CORS localhost:8080.

-After that he told me to make a route that would take a value in backend and store it in user as well as staff model.

Times asked 1
Official solution

Simplemodels.py = har table ki class: columns, PK/FK, relationships. Yeh Model layer hai.
Suggested flow1) Classes list karo
2) Har table ka kaam 1 line
3) Relationships (1-M / M-M)
4) Constraints (unique, nullable)
Example
```
class Lot(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(80), nullable=False)
    spots = db.relationship('Spot', backref='lot', lazy=True)
```

Advice: He might be the nicest proctor ever...I was very nervous and was not able to hear him correctly...He repeated every single sentence 15 times calmly. I made handful of silly mistakes as I was not able to understand what I had to do...still he was very calm throughout and made me correct every mistake I made himself and told me how should I solve the problem. It didn't even feel like I was giving an exam. Felt like he wants the students to pass and see pass through their nervousness and mistakes.
