SmartStream Technologies Senior Java Developer interview questions

Simple words, Dont go there and waste your time , I got call from Consultany and after screening interview got scheduled. Interview came and he asked me to write the program on Factorial number, I was shocked as nobody ask you write these programs on fresher level , I completed the program but then he ask me to write it using recursion , and yes, I was confused but wrote it at the end , after that he left the cabin and HR came and she asked me to leave. I was disappointed knowing that I wasted my time and please you can not test the candidate knowledge just on basis of 2 programs and worst was interview did not have the courtesy , he left without uttering any word. Please be cautious while appearing for interview
