Amazon Software Development Engineer SDE I interview questions

Was asked two medium interview problems. Was able to code both the problems but was not sure of coding was correct since there was no option to run the code. The interviewer gave me positive feedback tho but didnt hear back from them.

1) They contacted me and I followed the instructions on a link. 2) I solved the code challenge which were 2 difficult questions about data structure (I recommend studying DFS and BFS) 3) Work Simulation: Little by little you solved work situations on a daily basis. 4) Work style: What do you prefer most between 2 options. 5) Finally, a survey of how the selection process was.
