Let's discuss them one by one.
Note: The following written points all are based on my opinion.
1. You will see a deplorable guys around you, as they come up with basic technical skills and sadly are at the Technical Architectures Position. So prey to the good before you work with such types of guys. (Here our gods are our managers :) )
2. Sometimes an ASSOCIATE SWE Can rule you, your team members, and your project too. So be prepared for it.
3. You need to work day and nights in some time (Weekends too), As I was worked till 3 am for project delivery. Even later you need to check in at the right time so no one is bothered about you.
4. You need to be ready with good miracle algorithms as they will ask any human impossible or paid plugin tasks for free of cost.
5. They will ask timeline for every work for as I said at the 4th point.
6. Keep checking your teams or outlook 24/7 as you will notice at any point in time. I saw such things here
7. I have seen a few people who are in my project, they are always pushing you into a bad situation. As they are always playing such safe games.
