Had phone screen earlier this week. Was asked ip to cidr question seen here: https://leetcode.com/discuss/interview-question/5743277/Databricks-L5-(SSE)-Technical-Phone-Screen-or-Cleared/

Seems they like asking this question a lot in screening regardless of level (L4/L5). Interviewer was fairly disinterested in convo, just hopped straight into coding (which is fine its just screening round). Needed refresher on binary representation for octects and masking which took 10 mins to fully understand.

Small mishaps like forgetting syntax for exponent in python (2**i) caused delay in writing out the rest of code and interviewer was not keen on use of Google to search it, but expected me to figure it out. Ultimately had a working (sub-optimal) binary conversion of ip address. Wrote out easier main function of preventing or allowing, but did not run it as interviewer wanted two minutes at end for questions though think the code would work find.

Waiting to hear back still.
