Pros

- A workplace where you can be involved in everything from scratch to finish - Boss is very willing to listen to other’s ideas and implement it. - Boss is transparent and willing to give feedback and guidance to help me improve. What I’ve learnt in Sigma School can not only be translated to other workplaces but also my life values - Different departments collaborate frequently which enables me to learn about new ideas and point of views from different perspectives and importance - Environment where you learn to solve problems and able to improve yourself in many different aspects.

Cons

- No cons for me, but you need to be able to do these 1. Learn by yourself at times 2. Trial & error for results. Boss doesn’t judge if it doesn’t work but find out the reasons why 3. Need to ask what you don’t know because no one will babysit you. If you don’t ask, then no one won’t know what you don’t know
