Interview was senior system enginner
He started with short introduction then ask me to open codepen.io

Questions-
1) Create an input box which accept number.
- If number is more than 10 than it input value should show 10 .
- If number is less than 1 then input value should show 1.
- else number
Based on input value number of<li>< tag will be generated.

For example, If value = 20 with will converted into 10 
Then 
<li>1</li>
<li>2</li>
.
.
<li> 10<li>

Follow up -: if I click on any <li> tag then number should double from previous value.

2) Implement promise.All() functionality.
3) write a pollyfill which gives us count of vowel in a string.
4) reverse a linked list
