I used to work from 9:30am - 6:00pm, five days a week.
I worked there for more than four months from April till August, 2016.
I worked on TEE(Trusted Execution Environment) which can improve the security of mobile phone, and I learnt a lot of things about mobile security and also improved my coding skills.
My co-workers were very good at these areas in this job and they were also very funny when we went to lunch together.
In all, my workplace was very productive and a great place to work.
