I applied through other source. The process took 2 months. I interviewed at Percona in Jan 2019
Interview
Percona has reached out to me. Everything was moving on smoothly, professionally and fast until the face to face interview, after which they dropped out of sight and off the face of the Earth, never providing feedback after promising to do so. Out of sight, out of mind... Glad not to be with them as this shows how they'd treat their employees.
Interview questions [1]
Question 1
The interview style is conversational, so it's hard to pinpoint one specific thing - typical questions about past deals, work king style etc.
