JOBSEEKER?

In a company, several different programs insert rows into a messages table which should later be parsed and inserted into appropriate tables. Consider the tables:

TABLE messages
  id INTEGER NOT NULL PRIMARY KEY
  type VARCHAR(30) NOT NULL
  data VARCHAR(100) NOT NULL

TABLE notifications
  id INTEGER NOT NULL PRIMARY KEY
  message VARCHAR(100) NOT NULL

TABLE alerts
  id INTEGER NOT NULL PRIMARY KEY
  shortMessage VARCHAR(15) NOT NULL

Create a procedure called ParseMessages, in the default schema, which should do the following for all rows in the messages table:

  • Insert all rows where the type is 'notification' to the notifications table with the message field being set to the data field of messages table.
  • Insert all rows where the type is 'alert' to the alerts table with the shortMessage field being set to the first 15 characters of the data field of messages table.

In both cases the id field should be the same as in the messages field.

See the example case here for more details.

MS SQL  
 

  •   Example case: Could not find stored procedure 'ParseMessages'.
  •   The messages table contains only notifications: Could not find stored procedure 'ParseMessages'.
  •   The messages table contains only alerts with less than 15 characters: Could not find stored procedure 'ParseMessages'.
  •   The messages table contains notifications and alerts longer than 15 characters: Wrong answer

Screening Applicants: The Good, the Bad and the Ugly

Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?

Not really. I was surprised to discover that many experts disagree with each other. Everybody praises their pet method and criticizes the others. Many of these methods look legitimate, but are based on...
