Paytm Interview Experience | On-Campus

Round 1:

TECHNICAL TEST (ONLINE)

It included basic array questions like dividing money according to given problem statement (mostly arrays) practice must do questions from gfg.

Round 2: TECHNICAL ROUND 1

after test we were around 16 to 18 students.

They asked me some puzzles(practice from gfg).  They focused on graph, tree, stack. questions were like :

1.to convert binary tree to BST .

2.Printing largest sorted nodes in bst,

3.how will you make queue from stack,

4.how to implement ALT+ TAB function (use stack and queue)

5.implement random(0-7) such that it can print 0-14  with every element have equal probability. (easy just try).

Round 3: 2nd technical round

after previous round we were only 9 students left.

in 2nd round they focused more on projects, CV, OOPS, more puzzles and aptitude.

ROUND 4: HR round

I was not able to go in that round as after technical  rounds all non computer background students were sent back home even though i cleared all technical rounds. Before HR all interviews took like 1 hr to discuss whether to allow non-computer science streams.  It happened in one of the famous university.
I mean this hurts.

Never loose hope.

I hope this experience and questions will help 🙂
