Hi Sir. Im a software tester ( manual ) with 1.5 years experience. I was looking for a job n attended an interview last week n got the offer. Thanks a lot. I prepared by refering to your videos only.

I have also cleared another company's first technical round.They asked test cases of fan, earphone, some testing types, agile, scrum, etc. They took 45 minutes also.

Tomorrow I have a second round technical interview . Sir, what should I expect for second round technical interview? Pls help.
