Could you please help me for designing a Talend job which checks for the completion status of job A and job B loads and triggers Job C.
You need to give a lot more information on this. This can be achieved in a multitude of ways, but we need to know more about what you want to do. For example, are these jobs supposed to be built using a Parent/Child framework (ie are the jobs you are monitoring running inside another job)? Are these jobs all running on the TAC independently? Are they running on different machines? Can they all link to the same database? Is there a database that can be used? Are you wanting something that is memory resident that will immediately receive notifications of job status changes or do you want to poll (running the job every few minutes?).....I could go on.
