    Time mein chalne wala code, aur design discussion.

  4. Bar raiser

    Caching ka LLD, database indexing jaise sawaal aur behavioural.

Postman apna India fresher interview process detail mein publish nahi karta (humare check ke time par). Yeh jaankari candidates ke reports par based hai - kai reports experienced roles ke hain, isliye fresher ka process alag ho sakta hai. Recruiter se confirm karein.

Postman interview questions aur answers

APIs

  1. 1.200, 201, 204, 400, 401, 403, 404, 409, 429 aur 500 - kab kaunsa status code?

    Interviewer kya check kar raha hai
    API ki bhasha.
    Kaise answer karein
    200 OK, 201 naya bana, 204 safal par body nahi, 400 galat request, 401 login nahi, 403 login hai par ijazat nahi, 404 nahi mila, 409 conflict, 429 bahut zyada requests, 500 server ki galti.

  2. 2.REST aur GraphQL mein kya fark hai - kab kaunsa?

    Interviewer kya check kar raha hai
    API styles.
    Kaise answer karein
    REST mein har resource ka URL aur fixed response. GraphQL mein ek endpoint, client batata hai kaunse fields chahiye - kam over-fetching, par caching aur complexity ka kaam badhta hai.

  3. 3.API versioning kaise karoge taaki purane clients na tootein?

    Interviewer kya check kar raha hai
    Backward compatibility.
    Kaise answer karein
    URL mein (/v1/), ya header mein version. Naye fields jodna safe; hatana/badalna breaking - uske liye naya version aur purane ko deprecation notice.

  4. 4.Ek API ke liye automated tests mein kya-kya check karoge?

    Interviewer kya check kar raha hai
    Postman tests jaisa soch.
    Kaise answer karein
    Status code, response time, response ka schema, zaroori fields ki values, galat input par sahi error, aur auth na ho to 401.

Machine coding

  1. 5.Request mein {{base_url}} jaise variables ko environment ki values se badlo.

    Interviewer kya check kar raha hai
    Postman jaisa feature.
    Kaise answer karein
    Regex ya scan se {{naam}} dhoondo, environment map se value daalo; value na mile to wahi chhodo ya error. Nested ya galat brackets par test.

  2. 6.Collection runner banao: requests ko order mein chalao aur ek ka response agle mein use karo.

    Interviewer kya check kar raha hai
    Practical flow.
    Kaise answer karein
    Har request ke baad response se value (jaise token) nikal kar environment mein set karo; agli request mein variables replace hon. Fail ho to rok do ya aage - option rakho.

  3. 7.Do nested JSON objects compare karke unka diff dikhao.

    Interviewer kya check kar raha hai
    Recursion.
    Kaise answer karein
    Dono ke keys par chalo: sirf ek mein ho to added/removed; dono mein object hon to recursive; value alag ho to changed - path ke saath (user.address.city).

  4. 8.Workspaces, collections, requests aur users ka database schema - sharing ke saath.

    Interviewer kya check kar raha hai
    Schema design report hua hai.
    Kaise answer karein
    workspace, workspace_member (user_id, role), collection (workspace_id), request (collection_id, method, url, body), aur role se permissions. workspace_id par index.

Bar raiser aur design

  1. 9.API responses ko kab cache karoge aur cache kab saaf karoge?

    Interviewer kya check kar raha hai
    Caching ka LLD report hua hai.
    Kaise answer karein
    Sirf GET aur kam badalne wale data ko. Key mein URL + user/zaroori headers. Data likhne par us key ko delete karo, aur TTL backup ki tarah.

  2. 10.(a, b) par composite index hai - WHERE b = ? wali query slow kyun?

    Interviewer kya check kar raha hai
    Indexing ki gehri samajh.
    Kaise answer karein
    Composite index left se kaam karta hai - pehle a se sorted. Sirf b se dhoondhne par index ka seedha fayda nahi. b par alag index ya (b, a) order.

  3. 11.Mock server ka high-level design - saved examples se jawab dena.

    Interviewer kya check kar raha hai
    System design.
    Kaise answer karein
    Har mock ka URL, request match karne ke rules (method, path, query), aur matching example ka response. Bahut users ke liye stateless servers aur cache.

  4. 12.Ek technical decision jo galat nikla - aapne kaise sambhala?

    Interviewer kya check kar raha hai
    Bar raiser behavioural.
    Kaise answer karein
    Decision kya tha, kab pata chala, kya badla, aur aage ke liye kya seekha - bina bahane ke.

  5. 13.Postman hi kyun - kabhi Postman use kiya hai?

    Interviewer kya check kar raha hai
    Motivation.
    Kaise answer karein
    Postman se kaise APIs test kiye, kaunsa feature pasand hai ya kya behtar ho sakta hai - specific.

Postman interview ke liye 7 din ka taiyari plan

  1. Din 1: HTTP, REST, status codes, versioning.
