How do you reply to an Upwork job invitation?

[Btaliat]

Clients on Upwork always send invitation to their freelancers. When this happens, clients will see the notifications on their platforms. With this they can easily decide to accept to go for interview where the clients will check if they are qualified or not to handle the task. You can as well check you email for the same notification. The clients always give the job description in the notification for the clients to decide whether to get it or not.
