Помните, тут Илон Маск собирался купить Твиттер? Пишут, что он отменяет сделку, потому что Твиттер: — Неправильно считал число фейковых аккаунтов — Не смог предоставить сведения об объёме спама — Открыто признал, что последние годы преувеличивал количество пользователей Кстати, по последнему случаю в прошлом году был крупный штраф от Твиттера собственным же инвесторам по результатам судебного иска. Твиттер заявлял о росте месячной аудитории, но скрыл тот факт, что дневная аудитория стоит на месте. Что, кстати, интересно: люди как бы реже стали в Твиттер заходить, но при этом общее количество этих людей росло. То есть, смотрите, крупная корпорация тоже, как и отдельный человек, может врать, делать хорошую мину при плохой игре, скрывать и преувеличивать и так далее. А ещё инвесторы на Западе умеют замечать такие штуки и штрафовать корпорации. Интересно, что у нас инвесторы, похоже, не умеют, иначе непонятно, почему у них не возникало вопросов к тем же публичным цифрам от ВКонтакте. Хотя в современных реалиях, видимо, ВК уже не стоит считать частным бизнесом, а скорее государственной корпорацией. Не уверен, что для Твиттера срыв сделки с Маском это прямо так уж плохо. Маск там почти силой хотел его поглотить и навести свои порядки, весьма своеобразные, в соответствии с его характером. Но репутационно, конечно, эффект не самый приятный. Хорошо, что я забил на Твиттер и перестал им пользоваться. #web

✨The STAR method is a powerful technique used to answer behavioral interview questions effectively. It helps structure responses by focusing on Situation, Task, Action, and Result. For analytics professionals, using the STAR method ensures that you demonstrate your problem-solving abilities, technical skills, and business acumen in a clear and concise way. Here’s how the STAR method works, tailored for an analytics interview: 📍 1. Situation Describe the context or challenge you faced. For analysts, this might be related to data challenges, business processes, or system inefficiencies. Be specific about the setting, whether it was a project, a recurring task, or a special initiative. Example: “At my previous role as a data analyst at XYZ Company, we were experiencing a high churn rate among our subscription customers. This was a critical issue because it directly impacted revenue.”* 📍 2. Task Explain the responsibilities you had or the goals you needed to achieve in that situation. In analytics, this usually revolves around diagnosing the problem, designing experiments, or conducting data analysis. Example: “I was tasked with identifying the factors contributing to customer churn and providing actionable insights to the marketing team to help them improve retention.”* 📍 3. Action Detail the specific actions you took to address the problem. Be sure to mention any tools, software, or methodologies you used (e.g., SQL, Python, data #visualization tools, #statistical#models). This is your opportunity to showcase your technical expertise and approach to problem-solving. Example: “I collected and analyzed customer data using #SQL to extract key trends. I then used #Python for data cleaning and statistical analysis, focusing on engagement metrics, product usage patterns, and customer feedback. I also collaborated with the marketing and product teams to understand business priorities.”* 📍 4. Result Highlight the outcome of your actions, especially any measurable impact. Quantify your results if possible, as this demonstrates your effectiveness as an analyst. Show how your analysis directly influenced business decisions or outcomes. Example: “As a result of my analysis, we discovered that customers were disengaging due to a lack of certain product features. My insights led to a targeted marketing campaign and product improvements, reducing churn by 15% over the next quarter.”* Example STAR Answer for an Analytics Interview Question: Question: *"Tell me about a time you used data to solve a business problem."* Answer (STAR format): 🔻*S*: “At my previous company, our sales team was struggling with inconsistent performance, and management wasn’t sure which factors were driving the variance.” 🔻*T*: “I was assigned the task of conducting a detailed analysis to identify key drivers of sales performance and propose data-driven recommendations.” 🔻*A*: “I began by collecting sales data over the past year and segmented it by region, product line, and sales representative. I then used Python for #statistical#analysis and developed a regression model to determine the key factors influencing sales outcomes. I also visualized the data using #Tableau to present the findings to non-technical stakeholders.” 🔻*R*: “The analysis revealed that product mix and regional seasonality were significant contributors to the variability. Based on my findings, the company adjusted their sales strategy, leading to a 20% increase in sales efficiency in the next quarter.” Hope this helps you 😊
