Please can anyone suggest me some of the interview questions asked to 3 month experienced manual testing engineer.
The questions one can expect with the experience of just a few months would revolve around the basics of manual testing and what they achieved in their time with the previous company. The practices they used and what role one played.
However it would be expected that one has a sound understanding of the concepts of manual testing.
You can always go through some blogs which list interview questions on manual testing to pace up your preparation.
