So, the Lido Learning SDE Intern interview process had a few rounds. Round 1 involved two coding questions: one was a variation of finding an element in a sorted array, and the other was an SQL query to find the second highest salary per department. Round 2 was more technical, asking about the internal workings of HashMap and ArrayList (dynamic array), plus a question about my projects. The final round was with a Manager and HR, where they asked about HashMap working and collisions again, a string manipulation question to break a paragraph into strings based on line breaks, and why I'm interested in Lido Learning. I got selected for the SDE Intern role!
