Hi Fam,

Received yet another link for eBay Industry Coding Assessment (OA).
Platform: CodeSignal

I decided to go ahead and improve my scores.

Complete in-memory database implementation:

Level 1 : Support basic operations to manipulate records, fields, and values within fields.
Level 2: Support displaying a record's fields based on a filter.
Level 3: Support TTL settings for records.
Level 4: Support Look-back operations to retrieve values stored at a specific timestamp in the past.

You need to complete each level to unlock/prceed to the next level.

Interface Skeleton:

public void set(int timestamp, String key, String field, String value) {}
public boolean compareAndSet(int timestamp, String key, String field, int expectedValue) {}
public boolean compareAndDelete(int timestamp, String key, String field, int expectedValue) {}
public String get(int timestamp, String key, String field) {}

public List scan(int timestamp, String key) {}
public List scanByPrefix(int timestamp, String key, String prefix) {}

public void setWithTTL(int timestamp, String key, String field, String value, int ttl) {}
public boolean compareAndSetWithTTL(int timestamp, String key, String field, int expectedValue, int newValue, int ttl) {}

Update: Didnt get any invite for Nov 7th - Nov 10th Hiring Drive.
