ROUND 1 : Online Coding test :
Site : Codility.
Duration : 2 hr
Total Qns : 6
2 Qns are easy ,
3 Qns are medium ,
1 Qn is hard .

Results were announced after 10 days or so . I got around 80% in the test . I made it to the interviews.

ROUND 2 : 1st Tecnical Interview : 85 mins.

Java and Cpp qns:
Introduce urself, Abt my project , My role in project , What would I rate myself in DSA . Explain class with code (screenshared) , Usage of access specifiers , Diamond problem in java , how to prevent it , how to achieve multiple inheritence in java , Data abstraction and encapsulation , Inheritence vs Aggregation , abt polymorphism , Virtual keyword in c++, what happens in backend when virtual is used (VTable and Vptr) , Name mangling in c++

C Qns:
Difference bw #include<stdio.h> and #include "stdio.h" in C , malloc , calloc , sizeof opr in C , static keyword

Network Qns:
HTTP vs HTTPS , DNS , IPV4 vs IPV6 , Firewall , Hashing vs encryption.

OS qn:
Semaphore and mutex , types of testing.

DSA Qns:
Hashmap vs Hashset , Stack vs queue and real world examples , Tree traversals

Coding Qns:
1.Recurive fibonacci code
2.Kadanes algorithm(indirectly)
3.Don't remember the qn correctly , but it was a medium qn and I was asked to only explain the logic and not the code.

Behavioral Qns:
How I keep myself updated
How do I handle multiple deadlines.

I actually aced the interview , except for the name mangling and virtual working qn.

ROUND 3 : 2nd technical interview : 85 mins
Directly jumped to tech qns without any formal introduction qns.
explain name mangling and VTable and VPtr(qns which I missed in 1st interview) , all cpp qns.... ,

Again HTTP vs HTTPS , mutex vs binary semaphore , critical section , page replcaement algorithms .

2 logical qns in which I answered only 1
And an in-depth jump into pointers concepts. 3 pointer codes was pasted in chat box and I was asked the output of those. I really struggled.( He understood that I am not good in pointer concepts).

DSA qns:
1.Given a number, find the largest prime no. that is less than the given number . It was very easy and I did it in a flash and explained the Time complexity . I was asked how to reduce the time compexity . I said we could use Sieve of eratosthenes which I didnt remember how to code and fortunately I wasnt asked to code it.
2.Reverse the words in a given sentence . It was easy . I started doing it with full confidence and the interviewer saw my confidence and asked me to code it inly using pointers without using string at all . I stumbled all the way and tried it for around 12 mins and I did somewhat okay and he said its okay.

I thought it was over for me, I had entirely lost confidence but to my surprise I got a call for HR interview after 1 week of 2nd interview.

ROUND 4: Hiring Manager interview : 35 mins
Abt me and my project,OOPS concepts , qns on my projects , pointer concepts(which i struggled in 2nd round) , google cloud(mentioned in resume) , what I know abt Norton , Why Norton ,Where do I see myslef 5 yrs down the line , abt my leadership skills, How I approach a new technology , Find angle bw hour hand and minute hand of clock(without formula).

After 2 days , I received mail saying I got selected and after 2 weeks received the offer letter.

GOOD LUCK GUYS!!
