Thoughtworks Application Developer interview questions

1)API hunt game - Really easy if you can call REST APIs. Was able to finish this in an hour. (This round was given from home.) 2)Code pairing - You have to read the Refactoring book by Martin Fowler before appearing for this round and their HR will tell you the same beforehand. Interviewer was very friendly and gave me some hints 1-2 times when I was stuck. Overall it went well. 3)Technical 1 - There was one object oriented design question(you have to model the classes, member variables, methods), they also asked me to implement certain method and will be checking on your overall approach, and whether you are following single responsibily principle etc., then also asked me to design some REST APIs, and some questions on Java8. 4)Technical 2 - This round was basically all about my current project, its architeture, and discussuion on its design, technologies used in the project etc. Open discussion and they just want to understand whether you have deep knowledge in the things that you have used in the project. 5)Manager + HR round - General managerial + hr questions 6)P3 round - Discussion on various social topics.
