title: Are the requests in "Collections" executed in Parallel in POSTMAN`
body: <p>I am using the postman for the first time and need to generate multiple requests.
  I added them in collections and it seems that they are executed in parallel. Whereas I want to execute them serially. </p>
  
  <p>Basically depending on the response of the first request I will decide whether I have to send the second request or not?</p>
  
  <p>How to do this?</p>
