- Create a BPMN model for the following process using your modeler Internal Security Forces (ISF) Hiring Process A typical ISF hiring process starts by narrowing down applications. Those chosen are asked to do a number of medical tests. At this moment we are not interested in knowing what are these tests. We will get the details later but for now we know that these tests can be done in any order, and that it may be required for some applicants to repeat some tests multiple times. The applicants who pass all medical tests will undergo a psychological evaluation and a fitness evaluation. Applicants who do well on both evaluations will be interviewed. If things go well on the interview, an applicant is hired in the ISF. Every time an applicant fails or is rejected, he should be notified. PS: Since there will many applicants, you should use multi-instance activities and pools
