Example of Promise: Fetching data from an API once.
Example of Observable: Listening to user input events continuously.

Interview Preparation Tips
They didn't value candidates efforts and time. Firstly they will not respond to email, calls and if they respond by any chance they will give any silly answers possible. After completing Assessment test and technical round on portal it was showing that I will get invite for HR round but on next all status was reset and i received the mail again for technical assessment . And after contacting to HR many times, they are saying that my assessment test was not cleared and when I asked if my test was not cleared then how did my technical interview happened and she was like test result are confidential and are only disclosed to internal team. And then I again asked then how come I received the mail that I have cleared the test, and on their portal it was showing that my previous rounds are cleared and she cut the call.
