Saw linkedin post from HR that they were looking for SDE 2  messaged her with my resume. Got a call within couple of hours and given the OA link

two questions
        1) OOPS - Need to design inerface and imp class - easy - done in 15 min
        2) DSA - using priority queue - hard - took 60 min

1) asked to explain the logic for the OA Answers
2) dive deep into priority queue internal working - how heap works internally for get , add , delete
3) Given group of  strings and threshold value  Need to return true if all prefix with size threshold are equal 
    explained the approach , time and space and gave the code 
    follow - up : what if strings are sorted ? can we reduce time complexity ? 
	

    1) quick intro both of them 
    2) challenges faced in current project
    3) need to decrypt a string. i/o - "bcd" k = 2 o/p - "zab"
    4) mainly focused on production ready code instead of logic - 
            Eg : where will your make variables ?  how you seperate this method etc.. 
    
    5) didn't share the feedback . But myself did well with some of her help 

1) Design uber - 
		Functional requirments , Non functional requirment , estimation of data , which db will you use

2) Asked java questions 
		multithreading - Design two thread to make race condition , atomic integer
		hashmap - how works internally ? , make keys as pojo , how will find duplicate internally 

3) what LLD patterns you know
	Factory design
	Builder pattern 
	stratogy pattern 
	singleton 
	
4) what is transaction ? 

1) big introduction from both side
2) explained my projects i have worked on 
3) conflicts with cross teams 
4) how you deal with negative feedback from your manager
5) explain how you approach the tech issue with non tech customer
