The interview happened after the fall semester career fair expo. There are totally two questions that being asked. One question is about basic search and another is about tree. I wrote the code in a paper and I am allowed to use any language including C, Java, or Python. The interview lasts about 1 hour and I received a take home programming assignment after that. The programming assignment asked you to do a sorting on the string form 1 to many files. If you passed the programming assignment, you will be invited to the company and do an onsite interview. Since I did not do well on the programming assignment, I did not make it to the onsite interview.
