Process was 2 technical phone interview on coderpad, then on-site with 3 interview with a lunch in between. All coding interviews were conducted using their pair programming method where you will talk and code while the interviewer will correct any syntax errors and give you pointers. Most questions are very practical and something you would be implementing in real life. The questions would stem from real world applications such as design sudoku or play scrabble rather than very CS based questions such as reverse a linked list or traverse a BST. Their goal is to see how you think through a problem. Through out the process the recruiter responds lightning fast with any requests or questions. Phone Interviews (1:1, 1 hour each): 1) I definitely bombed my first phone interview. This was an odd question out of all the other questions I've been asked at Square. It was a very tricky graph problem where it's you know it or you don't. I first stated a brute-force solution but the interviewer asked to make it faster, I then talked for a solid 45 minute about optimizing and finally got to the result after many hints. I did not write a single line of code. However, I think Square still goes for a second phone interview as long as you weren't completely incompetent. I received a second interview invite 2 days after this interview. 2) The second phone interview was really good in my opinion. It was another graph problem but I was able to get a good solution within 10 minutes and built on it as we go, I had 15 minutes left to ask questions. I received an on-site invitation 1 day after this interview. On-Site (1:1, 2:1, 1 hour each): Square was very accommodating with flight, hotels, gas, and food reimbursements. The on-site was about 4-5 hours and consisted of 2 pair programming interviews, a lunch with one of the Software Engineers, a Q&A segment about my background, and ends with a HR conversation about next step. Some of the interviews were conducted by 2 people in order to train their Software Engineers to be future interviewers themselves. At the end of the day, HR gave me a bag of goodies. Some pointers is to relax during the interviews and talk with your interviewer. I believe my down fall was jumping into solutions too fast for some of my on-sites. I missed a very obvious solution because I was thinking way too complex and only got it after some hints. I had running solutions for all of my interviews but received my rejection one week after my on-site. Overall the experience is the best experience I have ever had. I have interviewed with very accommodating companies such as Google, Adobe, etc. but Square definitely takes the cake.
