Pros
if you are going to be deployed in to some client location then only you can grow in your career.
Kontras
People here believe we can test a product without SRS or CRS, test scenario and test cases, we can learn any programing language within 3 hours and prepare a POC and we can get that project to the company. When it wont happen they will tell you, you are not technically fit. It happened with me and sales guy started spreading because of me they last that project. May be he is not aware that my manger changed entire code submitted by me while reviewing and because of me they last this project (it happened when they forced me to automate with appium and they gave me only one day to setup and learn appium and 1 day to prepare POC and i had less than 3 years of experience). When you have some doubts or need some clarification and need to communicate with client they don't agree they will tell you let them come back when they get this issue. They believe we can handle any issues in webpage by changing some script or settings in local machine used to test the product. when you say its not in our control again you are not technically fit.
