Candidate interview experiences
First-hand accounts from people who interviewed at Gwynnie Bee.
Software Engineer
First two rounds were pen and paper, one for technical aptitude covering DS, OS, DBMS, and reasoning, and the other with 3 coding questions. We had to write complete code and time complexity on paper for the coding questions, which were quite interesting and took 2 hours total. After that, there were 3 technical rounds and 2 HR rounds (one was a phone call). The first technical round focused on coding, algorithms, and puzzles. The second was completely resume-based. The third was again on algorithms. The fourth was a formal HR question, very friendly. The fifth was another HR call.
- How many trailing zeroes are there in the factorial of a number, and can you prove it?
- Can you solve the 100 doors puzzle?
- Explain DFS and map. Also, discuss one of the algorithms questions from the written round.
Software Engineer
I went to their Bangalore office for 2 interviews back to back. The first one had some puzzles and Java questions you'd need to memorize. The second interview was about DS and algorithms. The first interviewer was an arrogant and not very knowledgeable person. Throughout the first interview, he acted like a bully and unprofessionally inquired in detail about the health reasons for my employment gap, then laughed about my health issue.
- Puzzles
- Java questions
- Data Structures and Algorithms
Software Engineer
It was a campus recruitment thing. The first round was a written test with MCQs in Aptitude, Computer Fundamentals, and Data Structures. The second round was also written, with 2 coding questions and 1 design question. Then, there were two technical interviews (third and fourth rounds) where they asked about OOP, Sql, data structures, puzzles, and my projects. The fifth round was a call with someone from the US office, mostly about my resume and HR stuff. The sixth round was a purely HR call from the Indian office. I actually thought their whole hiring process was pretty good.
- Can you find the longest bitonic subsequence?
- How would you print all coordinates of an element in a 2D matrix, considering duplicates?
- Explain Kardane's algorithm.
