  1. 1
    difference b/w get and post
    Times asked 1
    Official solution

    SimpleGET data read/show karta hai (idempotent). POST create/submit karta hai (form).

    Example

    @app.route('/login', methods=['GET', 'POST'])
    def login():
        if request.method == 'POST':
            # validate + session
            ...
        return render_template('login.html')
Advice: examiner was very patient with the project demonstration and also very chill and relaxed...dw too much just make sure yk minor code changes as well
  1. 1
    - shown id
    Times asked 1
    Official solution

    SimpleCamera pe clearly college/IITM ID dikhao — naam aur photo match hone chahiye.

    Viva tipPehle se ID haath mein rakho, glare mat aane do. Iske baad GitHub + project run.

  2. 2
    -explain admin creation functionality
    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.

  3. 3
    -post vs put
    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.

    Which function have you used to connect backend and frontend? One more question was asked about SQLite but I can't recall
    Times asked 1

    Jinja code for loop 5)Code for route with PUT and POST method

      <tr><td>{{ loop.index }}</td><td>{{ u.email }}</td></tr>
    {% endfor %}
Advice: He is very polite and professional. He usually asks the same basic questions, like the Jinja loop code, so be prepared for that. He doesn’t go too deep — just the fundamentals. At the end, he said I did very well, that my project seemed good (though I know it’s not great), and he also advised me to prepare for the Level 2 Viva. If you get this examiner as your proctor, consider yourself extremely lucky.
