A friend from Facebook referred me. A recruiter called me few days later.
She sent me an email, asking general questions like: "When do you graduate? How often do you code? Strongest programming languages?"
After answering the email, I had an initial chat with her over the phone, where she asked general questions like: "What office do you prefer? Would you consider a position in UK after the internship?"
One week later I had the first technical interview. The interview started with 5 minutes of questions about my work, then we jumped into one coding interview question. The question was simple: Write a function which given two binary numbers as strings returns the sum of them in binary. 5 minutes for my questions at the end.
Few hours after the interview, I got an email from the recruiter saying that the feedback is very good and they would like to schedule the final interview.
The last interview was easier than the first one: "Given a list of strings, return a list of lists, where each list consists of words that are anagrams." Example: Given ["cab", "cz", "abc", "bca", "zc"] the output should be: [ [ "abc", "bca", "cab"] , [ "zc", cz"]]. I managed to finish this question quite fast (after only 15 min). The interviewer wanted to finish the interview after 15 minutes, but I insisted to get another question. The next question I've got was even easier: "Write a function which returns the nth number of Fibonacci". When I've seen the question I jumped straight away implementing it (took me like 2 minutes), then we compared the iterative method with the recursive one.
After the interview, I got an email from the recruiter saying that my coding skills are very good, but the interviewer complained about the fact that I was a bit careless when answering the questions, and that I didn't explained him the Fibo solution before writing code. They wanted to schedule another interview.
One week later I had the last interview, which was some kind of giving me another chance, because they usually have only 2 interviews.
The last interview was much more difficult than the other two. The first question was: "Write a recursive function which given a string, prints all the subsets of it." After solving this question, he added one constraint. Now what if you want only unique solutions? This was quite hard, and I only managed to solve it after he gave me one important hint.
The second day I received a standard rejection email.
