  11. 11
    Overall she was really nice and supportive. The viva lasted around 30 minutes. She joined 10 minutes early as my slot had been postponed by an hour but was also willing to give me time to prepare more if needed. She also let me rewind and restart a theory related answer from the beginning since I was struggling a bit to structure it at first. Also asked if she had any suggestions for me and she said she was impressed by my project and she didn't have a suggestion.

  1. 1
    Introduce yourself and show your College ID.
    Times asked 1
    Official solution

    Simple20-30 second intro, phir ID nikaal ke rakhna.

    Example'Namaste, main <Name> hoon, IITM BS degree, MAD-1 project <ProjectName> — Flask, SQLAlchemy, Jinja. Roles: Admin, Staff, User. CRUD, auth, search implement kiye.'

    Interest poochhe to ek genuine cheez (ML, web, cricket) + 1 line. Fake buzzwords mat maaro.
    End mein feedback maangna theek hai: 'Koi improvement suggest karenge?'

  2. 2
    Give a complete demo of the project.
    Times asked 1
    Official solution

    SimpleDemo script pehle se practice karo, 5-7 minute, saari roles.

    Suggested flow

    1) Register/login user 2) Admin login — CRUD 3) Approval/blacklist 4) Booking/apply 5) Search 6) Validation edge (slots 0, duplicate) 7) Logout
    Bolte-bolte dikhao: 'Yahan overbooking rokta hoon'. Code tab kholna jab poochhein.
    Crash ho to debug calmly: terminal error, typo, DB path.
    Mandatory features skip mat karna — examiner list tick karta hai.

  3. 3
    Create a new service.
    Times asked 1
    Official solution

    Yeh project-specific feature add/modify hai. 4 layers touch karo: model, route, template, validation.

    1) Data chahiye to models.py mein column/relationship + DB update (ALTER / migrate / create_all).
    2) Route: GET pe form/page, POST pe request.form se save, flash + redirect.
    3) Template: input name=... Jinja se {{ obj.field }} display.
    4) Rule: duplicate, range, role check backend pe.

    Example naya field 'city':

    user.city = db.Column(db.String(50))
    user.city = request.form.get('city')
    <input name='city'>  ...  {{ user.city }}
  4. 4
    Register a professional for the newly created service.
    Times asked 1
    Official solution

    Yeh feature demo hai. Account ready rakho, steps bol ke dikhao.

    Role ke hisaab login → action (create/approve/book) → DB/UI pe result → edge case (fail when slots=0 / blacklisted).
    Do browser windows: admin + user. Search/filter alag se dikhao.
    Agar feature nahi hai to sach bolo aur 2 minute mein kaise add karoge (query + template) explain karo.

  5. 5

  6. 6
    Accept the service request.
    Times asked 1
    Official solution

    Yeh MAD-1 viva question tumhare project ke context se linked hai. Short answer is structure se do:

    Pehle 1 line definition/purpose, phir tumhare project ka example, phir chhota code/flow.

    Typical Flask flowBrowser request → @app.route controller → SQLAlchemy model/DB → Jinja template response.

    Auth: session['user_id'] + role check. CRUD: add/commit, query.all, field update, delete.
    Live change maange to: related model → route → template, phir browser refresh karke dikhao.

    Example (generic create):
    obj = Model(name=request.form.get('name'))

    db.session.add(obj); db.session.commit()
    return redirect(url_for('list_view'))

    Explain the frontend and backend architecture.
    Times asked 1
    Official solution

    SimpleFrontend user jo dekhta/click karta hai, Backend server logic + database.

    Frontend: HTML, CSS, Bootstrap, Jinja templates, thoda JS. Browser pe chalta hai.
    Backend: Flask routes, SQLAlchemy, session, validation. Python server pe.
    Data flow: form POST → Flask request.form → DB save → render_template/redirect → HTML dikha.
    MAD1 typical stack: Flask + Jinja + SQLAlchemy + SQLite + Bootstrap.

  10. 10
    Explain the tables used and their relationships.
    Times asked 1
    Official solution

    Examiner code pe ungli rakh ke poochta hai — panic mat karo, 4-line formula bolo.

    1) Yeh file/line kya role hai (model / route / template / config)?
    2) Input kahan se aata hai (form, URL <id>, session, JSON)?
    3) DB pe kya query/write?
    4) Output kya (render_template / redirect / jsonify)?

    Example

    @app.route('/book/<int:id>', methods=['POST']) — logged-in user session se, trek id URL se, Booking add, slots--, redirect history.

    Unknown line: imports (request, url_for, flash), decorators, if checks, commit — har keyword ka reason ready rakho.

  11. 11
    Show and explain the ER Diagram.
    Times asked 2
    Official solution

    Simplemodels.py har table ki class hai — columns, PK/FK, relationships. Yeh Model layer hai.

    Viva mein file khol ke bolo:
    1) Kaunsi classes/tables hain (User, Role-specific, Booking...)
    2) Har table ka kaam 1 line
    3) Relationships: 1-1 / 1-M / M-M, backref, cascade, lazy
    4) Constraints: unique email, nullable, default status

    Example skeleton

    class User(db.Model):
        id = db.Column(db.Integer, primary_key=True)
        email = db.Column(db.String(120), unique=True, nullable=False)
        role = db.Column(db.String(20), default='user')
        bookings = db.relationship('Booking', backref='user', cascade='all, delete-orphan')

    ER diagram: rectangles entities, lines relationships, PK/FK mark. Schema = yahi structure.
    Tables create: db.create_all() ya migrations. SQLite file SQL viewer se dikha sakte ho.

  12. 12
    Explain how authorization and role-based access control is implemented in the code.
    Times asked 1
    Official solution

    SimpleRBAC = Role-Based Access Control — permission role se (admin/staff/user), har user pe alag nahi.

    user.role = 'admin'
    if current_user.role != 'admin': abort(403)

    Same login page, role ke hisaab dashboard. Multiple roles: roles table Many-to-Many, ya comma field (behtar normalized table).
    Unapproved staff: is_approved flag, login pe check.
    Flask-Security/UserMixin is_authenticated, is_active, get_id dete hain.

  13. 13
    Explain template inheritance and show where it is used.
    Times asked 1
    Official solution

    Simpleextends poora layout inherit karta hai, include chhota piece insert karta hai.

    extends: child page base.html ka structure use karti hai, blocks override karti hai. Ek hi parent.
    include: navbar.html / footer.html jahan chaho insert. Kai baar use ho sakta hai.

    base.html:

    {% block content %}{% endblock %}
    
    home.html:
    {% extends 'base.html' %}
    {% block content %}<h1>Home</h1>{% endblock %}
    
    {% include 'navbar.html' %}  → navbar har page pe

    Fayda: header/footer ek jagah, change once — saari pages update. MAD1 mein almost har project use karta hai.

  14. 14
    Why did you use Jinja?
    Times asked 2
    Official solution

    SimpleJinja2 Flask ka template engine hai. HTML ke andar Python-jaisa data print/loop/if kar sakte ho.

    Bina Jinja har user ke liye alag HTML file. Jinja se ek template + data.

    {{ user.name }} print, {% for x in items %} loop, {% if %} condition, {% extends %} layout.

    Example routereturn render_template('dash.html', treks=treks)

    dash.html: {% for t in treks %}<li>{{ t.name }}</li>{% endfor %}

    HTML files templates/ folder mein isliye kyunki Flask default wahan dhundhta hai. render_template Jinja ko run karta hai.
    Boolean Jinja handle karta hai: {% if user.is_admin %}.

  15. 15
    Difference between Authentication and Authorization.
    Times asked 20
    Official solution

    SimpleAuthentication poochta hai "tu kaun hai?", Authorization poochta hai "tujhe yeh kaam karne ki permission hai?"

    Authentication: login. Username + password check karke prove karte ho ki tum genuine user ho. Success pe session/token milta hai.
    Authorization: uske baad role check. Admin hi parking lot delete kar sakta hai, normal user nahi.

    Example (Flask):
    # Authentication

    if user and check_password_hash(user.password, form_password):
        session['user_id'] = user.id
    
    # Authorization
    if session.get('role') != 'admin':
        abort(403)  # logged in ho, lekin allowed nahi

    Project example: student login = authentication. Student admin dashboard nahi khol sakta = authorization.
    Validation alag cheez hai (form sahi bhara hai ya nahi, jaise age 18+).

  16. 16
    Which database engine are you using? (SQLite)
    Times asked 1
    Official solution

    SimpleSQLite file-based chhota DB, MySQL/Postgres server-based production DB.

    SQLite fayde: zero setup, ek .db file, MAD1/dev ke liye perfect, portable.

    Nuksaanconcurrent writes kam, user/password nahi, network access nahi, production scale nahi.

    MySQL: users, permissions, concurrent, replica. App factory mein URI change karke switch: sqlite:///app.db → mysql://...

  17. 17
    How are user ID proofs, photos, and other uploaded documents stored securely?
    Times asked 1
    Official solution

    SimpleFile upload form multipart, Flask request.files, disk ya DB path store.

    <form method='POST' enctype='multipart/form-data'>
    f = request.files.get('resume')
    f.save(os.path.join('uploads', secure_filename(f.filename)))

    Sensitive docs uploads/ web se seedha serve mat karo, login check ke baad send_from_directory.
    Student resume edit: policy — allowed hai to Update route, nahi to freeze after apply.

  18. 18
    Is anything (such as session cookies) stored on the client side?
    Times asked 1
    Official solution

    SimpleCookie browser mein save hoti hai, Session server pe data rakhta hai aur browser ko sirf ID deta hai.

    Cookie: key-value browser pe. JS padh sakta hai (agar HttpOnly nahi). Size chhoti (~4KB).
    Session: server-side dict. Flask default mein session data signed cookie mein hi store hota hai (client pe, lekin tamper-proof).

    Example

    session['user_id'] = 12 # login ke baad
    # browser ko Set-Cookie milti hai

    Tab close: default Flask session cookie browser close pe delete (session cookie). Permanent session alag hota hai.
    Incognito: cookies isolated, isliye logged-in nahi dikhega.
    SECRET_KEY se session sign hota hai — key nahi to session insecure/kaam nahi karega.

  19. 19
    Why don't you have a cart system in your application? (Justify your design choice.)
    Times asked 1
    Official solution

    Definition style question: 1 line simple Hinglish + project example + mini code.

    Template'X ka kaam Y hai. Mere project mein Z jagah use hua.'

    Example'Session login state rakhta hai. session[user_id]=u.id login pe, logout pe session.clear().'

    Agar topic Vue/Celery/Redis ho aur project mein nahi hai to sach bolo, theory example do.
