Ho presentato la mia candidatura tramite segnalazione di un dipendente. La procedura ha richiesto un giorno. Ho sostenuto un colloquio presso Fiserv (Noida) nel mese di lug 2019
Colloquio
There was just one interview held for me.
It required Java and Struts MVC.
However, they were comfortable with someone having experience in any MVC framework.
I believe the work wasn't going to be much challenging.

Domanda 1
class level locking vs object level locking
ways you can create threads
Thread vs Runnable
Database structure - lets say you have Employee table which can have multiple projects and Project table which can have multiple employees then how would you structure your tables?
My Answer -
Create Employee table having EID and its other attributes
Create Project table having PID and its other attributes
Create Relation table having EID and PID where multiple EIDs are possible for one PID AND multiple PIDs are possible for one EID.
Try with resources (as per Java 7 onwards) problem with employee say try(Employee e=new Employee()) {} <- Is this a problem? If yes, why?
Why do we favour composition over inheritance
App context vs web app context
Servletcontext vs servletconfig
Loadonstartup in web.xml
Cyclic/Circular dependency in spring
Constructor injection vs setter injection? Which one would you use and when?
transaction management in spring, isolation, propagation, where do you put transaction - Service layer or DAO layer?

Colloquio
Seemed very straight forward. Nothing out of the ordinary as far as interview questions go. But I didn't receive either a positive or negative response after the interview, and that seemed slightly unusual.
I have never in my life seen a worse company who actively does their best to ensure they waste your time and have nothing to show for it.
I was reached out to almost a year ago about an SDE role. I was told there were going to be 2 interviews (technical and final). Those two turned into four with two "we're not sure if we're going to hire for this role". I went through a significant amount of stress and constant follow ups with no end in sight. For this one job alone I had to deal with multiple recruiters. Again, I have never seen such an egregious amount of effort put in to ensure my time and hopes of getting a job are wasted. Fiserv should be ashamed but I know they wont care because of this employer advantaged market right now.

Domanda 1
Database locking, multithreading, and other concepts.
It was easy and smooth with total 3 rounds including technical, managerial and HR.
A panel of 2 were there in each of the first two rounds. Easy to crack the interview.
