Localytics Software Engineer interview questions

Telephone with recruiter - > 1 hour coding challenge -> 1 day interview The recruiter asked me what time I want to give the coding challenge and he sent me the email with question and 2 tsv files at that time. I had to email the answers and my code in 1 hour. So you code the solution and get the answers. In the 1st call, the recruiter will ask you if you know scala and if you dont know scala, they will still send you the coding quiz but you dont stand a chance. I used a parser to parse the tsv files and also got the answers using hashmap in java, but the recruiter told me they didnt like my solution. Well, I wished them all the best in their search and got a better company and better job.
