Interview Questions

Danny - "There are way more learning opportunities for us here if we acknowledge that this was not a good example and provide tips on how to improve the answer. All the answers here are superficial and it is clear that the interviewee was unprepared. . The mention of quote "a wise man told me..." (instead of getting to his own personal points) and some lack of confidence with the metrics portion are red flags. . For more concrete example, it is hard to believe that no one wants to fix the slow build proc"See full answer

Kari J. - "I got this question in my Mini-Case today. I was a little confused because even though I asked a few clarifying questions -- it didn't clarify much! :-) My response was to what was shown on screen -- a mock of the current process (five modal windows) and a mock of a new single modal. THe ask for this was what do you like and dislike in the mock for the new. I will admit that it would have been easy to say what was wrong with the current process - but since the ask was for the new mock, and"See full answer

Ankita K. - "Clarifying questions: What is user frustration/ Define user frustration? Was this qualitative feedback, or some reviews on playstore or support that we saw recently or some drop in metrics or increase in churn, or overall churn that we are addressing? Let's assume frustration leads to users quitting the app and hence an increase in churn. This churn also indicates that users leaving the app after trying out a particular feature and not doing the core action of seeing the route from point A to p"See full answer

Alice S. - "Clarify understanding of the problem space. What does success look like? How is it measured? Platform specific? Market specific? Time period? Business goals? Then perform a funnel analysis to understand user journey and look for problems or opportunities. Choose a user segment to focus on. Identify different user segments and prioritise one. Summarise the goal of the user and the friction point. Brainstorm solutions. Come up with a number of rough solutions. Balance the business n"See full answer

Kartikeya N. - "Clarifying questions I am assuming the time frame for this question is irrelevant as this is a hypothetical question? : Yes Is IG prioritising the creator side or the viewer side more at the moment? : What do you think? I think it should be a balance for the long term sustenance of the network Are all these reels and views in a particular geography or globally? : Globally What is the duration for which these Views are measured?

Sebastián N. - "Mission-first doesn’t mean ignoring revenue; it means optimizing for the right revenue. For me, it looks like: ( I qualify for legitimate use cases and clear success metrics; I’m transparent about limitations and risks; I escalate edge cases early rather than trying to ‘get creative’ to save a deal; and (4) I’d rather slip a quarter than sign a customer into a deployment that’s likely to cause harm or blow up trust later. Practically, I manage this by building pipeline that matches our ideal cus"See full answer

Kartikeya N. - "C : Okay. So I would want to start with knowing what is the product for which we have to build a recommendation system. I : This is a photo sharing product. C : Okay. So is this something on the lines of Instagram? I : Yes C : Okay. And are we a new product co or we have some current product built already? I : You can assume yourself. C : Okay.

Mehul K. - "Clarifying Questions Are we building feature for YouTube Music/YouTube Video? -> YT Video has higher scope of user engagement so YT Video. YT Video has 2 forms of video content, are we focusing on long form, short form or am I free to chose ? -> YT Shorts and short videos have taken off lately so focus on it. Do we have a specific business goal with regards to building this feature ? -> We want to improve engagement. Do we want to build this feature for a specific kind of audience or"See full answer

Varun G. - "If I launched a feature users love but that isn't driving business value, I'd first validate whether we're measuring the right metrics — then systematically test monetization paths before deciding to scale, pivot, or kill it. Step 1: Diagnose the Gap I'd start by understanding why engagement isn't translating to business impact. The problem usually falls into one of three categories: Wrong user segment: The feature attracts users who don't convert or have low lifetime value **Mis"See full answer

Patrick B. - "Clarify what the business goals of Spotify is Depending on the stage, some companies care more about revenue growth, some about user growth and in rarer cases, about profit margins.

Jazmia H. - "Weak point: suggested something that YouTube Music already does- offering the service free to Premium members.

Settled on discussing an innovation piece combining ranked recommendation of YouTube music as well as personaliz"See full answer

Alfred O. - "We can use dictionary to store cache items so that our read / write operations will be O(1). Each time we read or update an existing record, we have to ensure the item is moved to the back of the cache. This will allow us to evict the first item in the cache whenever the cache is full and we need to add new records also making our eviction O(1) Instead of normal dictionary, we will use ordered dictionary to store cache items. This will allow us to efficiently move items to back of the cache a"See full answer
