Broadcom Software Development Engineer SDE interview questions

about projects, basic dsa question about returning true if number is repeated in array and false otherwise, second questoin about returning count of repeateed nubers, maybe thry would have asked more questions but i really messed it up until this point and failed to do second question cuz i did not revise dsa nor language for a long time . but just prepare basic dsa and describe your projects in detail, i hope this helps !
