Good interview, scheduled fast. The only minus was the 30-minute presentation of the company (even though I told them I worked there before).

The interview included:

• Algorithms (live coding in Java)
• SQL
• Questions about Java

I aced the first two. Sadly, I'm not senior yet. I would have passed as an "advanced" Junior, but they weren't hiring in that grade at the moment.

Write code separating odd and even numbers in a table to separate ends.

In SQL, find all clients with at least 3 projects.

Java questions:

• How to store passwords (byte array)
• Favorite design pattern
• SOLID - in your own words
• What is coupling? (Heard 'cupping' and answered comparing coffee.)
• Passed on Spring (was working with Guice before).
• Inner implementation of HashMap.
• Java memory management.
• Difference between orElse/orElseGet.
• Example of a functional interface (Predicate).
• Streams.
• Terminating operations.
• String comparison questions.
