Given an interface called IntStream with methods 'bool hasNext()' and 'int next()', implement the function 'IntStream merge(IntStream[] streams)' where each input IntStream produces strictly increasing, possibly infinite number of, integers, and the resultant IntStream also produces strictly increasing integers by merging the input streams. The interviewer also provides a simple test harness that prints the first 5000 integers from that function.
Give a presentation on a topic you select.
JS, SQL, NoSQL, know fundamentals
Asked a lot of questions revolving algorithms and other core CS concepts. Only one of the interviews was specific to the actual job being applied to (core web and frontend).
Name standard library Interfaces in Java
What Service in AngularJS does
Recall a situation when you have to get an answer from smb who is not there
The process was pretty complex and it was simplified a bit since then, and it was pretty impressing. They don't do any silly gotcha coding questions. They do test basic CS fundamentals pretty heavily, but they are smart about it. Mobile platform questions. Simple coding question in Java, Objective-C and C++, questions about platform API (basics to check if you really code in it), and multithreading concepts. Take home assignment - optimization problem (I believe they don't do it any more) with elements of OOD. On-site coding round (leetcode style puzzles, basic CS concepts, data structures, threading, memory management, code review). On-site design round. Designing complete mobile app, frontend and backend (architecture, no visuals). Discussing various constraints, changing requirements as you go, to check if your design is adaptable. On-site company culture fit round with manager. HR round with compensation expectations. On-site team culture fit round with direct team lead.
Tell me a time when you had to break the rules or do something unethical.
The interview had 3 rounds - 1st Round: It was a technical round. They asked which subjects are you familiar with. They asked one simple coding question, using different approaches. ( like for loop, recursion, top-down/bottom-up) . and few questions related to OOPS. 2nd Round: This round was also technical. They asked questions related to Stack DS, applications of OOPS, and one simple coding question. Since the role was related to SW Application they asked questions related to Web development. About HTML, CSS-related borders, padding, etc... 3rd Round: It was around 10-15 minutes.
