Process
Step 1: As the cache is initially empty, the main memory provides P1 with the block, and it enters an exclusive state.
Step 2: Since the block is already present in the cache and in an exclusive state, P1 directly modifies it without any bus instruction. The block is now in a modified state.
Step 3: In this step, a BusRd is posted on the bus, and the snooper on P1 senses this. P1 then flushes the data and changes its state to shared. The block on P3 also changes its state to shared as it has received data from another cache. The data is also written back to the main memory.

Qualcomm Work Experiences
- 4.0Great Benefits, Hectic WorkSenior Software Developer • Former EmployeeWhitefield, IndiaSeptember 19, 2023Pros: Apart from salary, benefits like medical insurance, 50% reimbursement on health membership, a 15k discount on Qualcomm products, breakfast, lunch, and snacks, car facility, tuition reimbursement, 6 weeks paternity leave, performance bonus, RSU, and ESPP plan.Cons: Working at Qualcomm, be it anywhere in the world, is the most hectic and appalling. They have no regard for their employees, and all they care about is getting the work completed at the cost of the employees' health. Work-life balance is deplorable. Rather than hiring more people, they try to squeeze in the maximum possible load on a person's plate, to the extent of making them work 24/7 (literally). Rather than doing so, they should spend some time on analyzing what can enhance their employee satisfaction. But no, they don't have time for such abysmal, petty things.
