My journey so far.

2017 - 3500
2018 (mid) - 4500 (adjustment)
2019 - 5000 (promotion)
2019 (mid) - 6500 (switched job)
2020 - 6800
2021 - 7200 (promotion)
2021 (mid) - 9000 (request HR for the increment)

I am planning to switch job next year actually. Road to 5 digits.

I am a software engineer, CS grad FCH but not from NUS unfortunately. My friend who graduated from CS NUS (average result), got 9k as a fresh grad.
