RNN
RNN (Recurrent Neural Network) is a type of artificial intelligence tool that's particularly good at understanding sequences of information, like text, speech, or time-based data. Think of it as a digital brain that can remember and learn from past information to make predictions or decisions. It's commonly used in creating smart applications like language translation, text prediction, or analyzing customer behavior over time. When you see RNN on a resume, it usually means the candidate has experience with advanced data analysis and machine learning projects. Similar technologies include LSTM (Long Short-Term Memory) and GRU (Gated Recurrent Units).

Example Interview Questions
Senior Level Questions
Q: How would you explain the vanishing gradient problem in RNNs and how would you solve it?
Expected Answer: A senior candidate should be able to explain in simple terms that RNNs can struggle with remembering information over long sequences, and describe solutions like using LSTM or GRU architectures. They should demonstrate experience in choosing the right approach for different business problems.
Q: Can you describe a real-world project where you implemented RNNs?
Expected Answer: Look for comprehensive answers that cover the business problem, why RNN was chosen, implementation challenges, and measurable results. They should explain their decision-making process and any alternatives considered.
Mid Level Questions
Q: What are the main differences between RNNs and other neural networks?
Expected Answer: The candidate should explain that RNNs are specially designed for sequential data, using examples like text or time series. They should be able to explain when to use RNNs versus other approaches.
Q: How do you prepare data for an RNN model?
Expected Answer: They should describe the process of preparing sequential data, including cleaning, formatting, and splitting into training and testing sets. Look for practical experience with real datasets.
Junior Level Questions
Q: What is an RNN and what are its basic applications?
Expected Answer: They should be able to explain that RNNs are for processing sequential data and give basic examples like text prediction or time series analysis. Basic understanding is sufficient.
Q: What tools or libraries have you used to implement RNNs?
Expected Answer: Look for familiarity with common tools like TensorFlow or PyTorch, and basic understanding of how to use them for simple RNN implementations.
