Signzy Software Engineer, Backend interview questions

1st Assignment round 2nd and 3rd Tech round on my project and NodeJS 4th round was based on architechture design in which employee named shiv who I dont know why showing so much anger instead he should get my explaination and give me little hint he couldnot make his question clear and I had to suffer because of him in the form of rejection. So I suggest him, please be polite and make the interview as a discussion not a battle.

Firstly the resume was screened when applied online . After the resume screening a confirmatory email was sent for further proceeding and detailing the how the selection process is gonna go through .Then a web scraping assignment was sent and to be done in the next day.After that a technical interview was scheduled in the next week
