Guidewire Graduate Java Developer Consultant interview questions

I got invitation for online coding test. It was 1 q, on doing somwthing with strings, very lengthy but easy. Then a phone call interview, and gosh I wish I had revised Java fundamentals back then. He asked series of qs (constructor overloading, different scenarios) and asked me what would be output of this and that, then basic qs what is interface, abstract, inheritance and in end one coding q, find how many times a string appear in another string? Bombed it
