Databricks concurrency interview

Round 6 of 8

See the whole loop
Length
60 min
Format
Live coding
They grade
Writing correct, efficient multithreaded code (for example a message-processing logger)
Heads-up
Most candidates call this the hardest round. Some loops make it a practical low-level round instead: a lazy array, run-length compression with bit packing, a log writer, file system tasks or a cache.
