The scheduled telephonic interview was rescheduled thrice. Finally, one interviewer conducted the interview and started by asking complex SQL queries (only two queries were asked in the entire interview). In between the telephonic call, the interviewer would leave the call. There were no questions on DWH or ETL testing. Overall, this was the worst interviewer I have ever encountered.

SQL Query:

There is a table called alphabet. It has a column named alpha with 6 rows containing the values 'a', 'b', 'c', 'd', 'e', and 'f'. I want to display 'feabcd' in the output.
