Round 1:

• Disussion on past project and web optimisations techniques. Questions around useEffect how it works and how it will output on a given code snippet. How react uses batching for updates.

• Output question on promises, something like this
  console.log(1);
  setTimeout(() => {
  console.log(2);
  }, 10);
  setTimeout(() => {
  console.log(3);
  }, 0);
  new Promise((_, reject) => {
  console.log(4);
  reject(5);
  console.log(6);
  })
  .then(() => console.log(7))
  .catch(() => console.log(8))
  .then(() => console.log(9))
  .catch(() => console.log(10))
  .then(() => console.log(11))
  .then(console.log)
  .finally(() => console.log(12));
  console.log(13);

• Write Pollyfill of useEffect

Round2:

• Questions related to web security
• Output Question like round 1
• Create step form in react with different fields and validations like start date can't be after end date etc. Every step has few fields and one save draft button. Save Draft will save values entered till that step and one final submit button.
