Chaayos is an exponentially growing Indian Startup of Network of TeaCafes.
I was recuited as their Summer Intern(2017) assigned to the RnD team for developing an IOT based machine.

The Technical interview was on call. I was asked to introduce myself and my hobbies. Then they asked me my technical interests and skillsets ihave developed in college. I answered in a very confident way. The icebreaking session did go very well.

Now, I was asked about Object Oriented Programming. Following are the few questions that I was asked by the interviewer-
1)Why do we need to use OOP in developing a simple IOT machine.
2)Why do we use public, private functions and what is the difference between them.
3)Can we call a member inside a private class from a public class and vice versa.
4)What is encapsulation.
5)Is multiple inheritance a necessary part of OOP.

These are some few questions I was asked. Some of the questions that I could not answer I frankly replied saying I donot know and will find the answers for it. They were happy with my confidence and truth.

Later as I did few projects onIOT and mobile development I was asked to explain them in brief and what all technical knowledge I gained from them. The interviewer was a young lad who was the senior software engineer at the company. Happy with my interaction, he asked me how and when can I joined the earliest and discused about my stipend. The call lasted for thirty minutes and not more. It was a very apt interaction and I really enjoyed the interview.
