Test Engineer is a broad term. I would look at the job description and prepare accordingly.
Here are some things you should look into:
- Types of testing: white/black box, functional vs non-functional, API testing, browser-based testing
- If you are asked to write test points for a function/form etc. make sure you cover positive, negative, edge cases, upper/lower limit etc.
What legal risks am I taking? If any.
Solo founder on H1B.
Working on a side project from couple of years.
Recently incorporated, B2C platform pre revenue.
Good luck!
