Mukul P. - "Here are some strategies to mitigate the effects of organizational and architectural dependencies on a team's work. Automation Where possible, automate repetitive tasks, and include appropriate controls to ensure safety. For example, automate deployments, building in all needed safety and compliance checks, and let teams perform the process themselves, rather than having them back up in the Ops team’s queue. Standardize processes Even if you can’t automate a process, make it happen the s"See full answer

Rohith K. - "Clarification - I will first clarify what is the data insights we are talking about? Is it a feature in the platform or are we talking about data insights that we use in our work? First listen and not judge - I will first try to understand what the engineer is talking about, what is the disagreement that he is raising. Context - Then I will try to ask the engineer if he has the overall context about the feature/solution/functionality he is talking about. If he has all the cont"See full answer

Catherine I. - "I always ask to clarify if this is a brand new team. If so, then I focus on bringing in people with strong technical aptitudes(since I'm hiring for software engineering), but also team members that have experience mentoring and good communication is a must. I look for people who have leadership qualities. I emphasize that building a brand new team isn't something I can do on my own, so the initial hires of that team are very important to help me expand it."See full answer

Bulent K. - "I said we could always revert the production issues. Solve it at DEV environment and then publish again. Interviewer gave me an example of it like a database schema change that may not be possible to revert. I said that we always used SQL scripts to upgrade and downgrade the database schema for each production deployment. So it would not be a problem for us. I guess my answer was not accepted."See full answer

M N. - "Why do we want to build an ad platform? Should we discuss if we should/should not do this? Or have we decided? Let's say we decided. Now what's the goal of ad platform? Additional revenue stream. We need to make sure the ads we show don't distract our users from the core product but help our users with their financial needs through relevant advertisements. It might not be a bad idea to monetize the 13M users as long as we're connecting them with the right brands/services. Now let's look at the"See full answer

Seth W. - "As always, I'd start this discussion by asking a couple clarifying questions. In particular, I'd like to learn more from the interviewer about what "not pulling as hard" looks like. Does it mean: lower code output relative to the rest of the team lower velocity per sprint in terms of story points less participation in code reviews minimal participation in meetings and ceremonies Or perhaps it's a combination of these. As others have pointed out, I'd also want to confirm that I am not ma"See full answer

Exponent - "The key to this is to be concise and specific. You won't need to code as a product manager, but understanding technology is important. Only give enough information to validate your knowledge. By speaking too much, you may make a mistake (if you're not technical). > Sure!
