Cause your company is lousy.
Come work under me. We do scrum.
Every sprint is 2 to 3 weeks.

Example first sprint I'll ask you to do an api to do the basic crud for one module.
That one 1 week should see base. After 1 week Friday afternoon, you need to demo to the team for code review.

Then i can see liao.if you pass, then will ask you to improve your sql. To avoid deadlock etc.
Then next sprint more function.
Then next sprint load test.

Within 1 month I can see how real is your sql python skills.
After we follow scrum we weed out all the fake one.

The zai one stayed. We increased their pay as reward. No question ask.
Till today those still wirh us.
Fake one come and go so fast. We make sure 1 month out they go.
Yes we ruthless. So don't try to fake us that you know docker, data analytics, ai. Cause we will assign you work to prove it.

Even if there is no actual work. We will take problem and assign to you.
We don't expect you to last 1 month.
