smartData Enterprises Software Engineer Interview Questions
& Process

So, the interview process started with an aptitude and technical MCQ round. Then, there was a technical round, followed by another technical interview. The last round was supposed to be for managerial/culture fit, but it turned out to be technical as well.

4 rounds total. 1st was MCQs on microservices, api, devops basics, easy quant and basic gk. 2nd was technical, discussing basic project and resume, and technologies and commands used. 3rd was technical, similar to the first technical interview, plus HR questions, technologies and projects, and how to incorporate AI/ML/IoT in websites, SAAS, PAAS, IAAS, Abstract class, and multiple inheritance. 4th was technical, focusing on system optimization, various tools and technologies, with an emphasis on AI, ML, and IoT.

I had two interviews. First was a technical round focused on Android development. They asked a bunch of questions about custom content providers, content resolvers, editing contacts directly, libraries for editing contacts, differences between XML parsers (sax, dom, pull), contact edit URLs, handling configuration changes with EditText, intent filter categories, intent services vs services, recent web services used, supporting multiple screens with different densities, the difference between sp and px, when to use sp pixels, details on push notifications, density pixels, density-independent pixels, why we use Activity.class instead of .java files, the difference between byte code and hex code, Thread.sleep() and Thread.wait() in broadcast receivers, explaining DDMS in detail, sending objects between activities using bundles, explicit vs implicit intents, SQLite databases, the difference between content providers and SQLite databases, and creating your own content provider. They also asked me to verbally describe the code for editing a contact. Additionally, they inquired about pending intents and sticky intents. The second interview was with HR, where they asked about my previous salary, current salary expectations, notice period, and my reason for leaving my current job.
