Questions were asked on database, data structures, ruby on rails: - Was given few entities and was asked to design a database from that information. - Was asked to write few queries. All were easy, using aggregate functions and group by clause. - Was asked few data-structure related questions like, How would you store a huge number of picture files and similar pictures should be together. What kind of data structure should be used and what will be its time and space complexity? - Ruby on Rails questions were related to my work experience.
