The phone screen was usual, but the onsite interview was very disappointing.

• Interviewers were remotely located. One of them was courteous enough to explain why he was remote, while the other did not bother introducing himself.
• The interviewer was unprofessional and extremely rude over the phone.
• After solving the coding problem on a shabby online tool that had major page loading issues, I was instructed to write tests.
• Halfway through writing the tests, I was commanded to go back and rewrite the entire code because the interviewer did not like the brute-force approach.

This was a clear sign of inexperience and immaturity. The hiring decision was clearly biased, as other rounds went smoothly.

The hiring manager was a nice guy, though there were clear signs of his lack of experience in hiring people.

Advice to management:

The interview panel speaks a lot about your team and company. Select them carefully and use feedback wisely.

Merge 2 sorted lists. Reverse words in a sentence: "hello world" becomes "world hello". Write an SQL query to join two tables. Write a method to return the extra character between two strings that contain the rest of the same characters. Ex: "abcd", "acedb" should output 'e'. Design a cache. What algorithm would you use for a file crawler? Basic Unix commands, Java, OO questions.
