Received my second set of GCMS yesterday, it gave me all the details till they made the final decision.
1. They made a web based search for my job experience, a minor hiccup when the case analyst thought my job title didn't match with my job duties. Nevertheless, it was cleared by the visa officer.
2. I claimed 4 months of experience on implied status, to which they initially counted 8 months of experience on my PGWP which of course reduced my score to 385, however this was too cleared by the visa officer.
3. They didn't verify my foreign experience, they just analysed that my education was in line with my foreign experience.
Fun facts:
1. They didn't touch my file for 3 months straight. When they did, they cleared it in 19 days.
2. Like how I assumed, they asked sch A only because they wanted to know the reason for 'yes' to their questions. When I explained them, they approved my file.
3. My file was approved 3 days before the final PPR request.
