Calsoft Interview Questions, Process, and Tips

Outliers are data points that significantly differ from the rest of the data, affecting mean, median, and mode.

• Outliers are extreme values in a dataset that do not follow the general trend of the data.

• Outliers can skew the mean towards their value, making it an inaccurate representation of the central tendency.

• Outliers have little to no effect on the median, as it is not influenced by extreme values.

• Outliers can affect...read more

RAG Chatbot and Multi Agentic RAG are architectures used for building conversational AI systems.

• RAG Chatbot is a retrieval-augmented generation model that combines retrieval-based and generation-based approaches in chatbots.

• Multi Agentic RAG extends RAG Chatbot to support multiple agents collaborating in a conversation.

• These architectures improve the performance and flexibility of conversational AI systems.

• Example: RAG...read more

RAG Chatbot Model is a single-agent model while Multi-Agentic RAG Model involves multiple agents collaborating.

• RAG Chatbot Model uses a single agent to generate responses to user queries.

• Multi-Agentic RAG Model involves multiple agents working together to provide more diverse and accurate responses.

• In RAG Chatbot Model, the agent is responsible for both retrieving and generating responses.

• In Multi-Agentic RAG Model, di...read more

Responsible AI refers to the ethical and fair use of artificial intelligence technologies.

• Responsible AI involves ensuring transparency in AI decision-making processes.

• It also includes addressing bias in AI algorithms to prevent discrimination.

• Responsible AI requires accountability for the outcomes of AI systems.

• Companies and organizations should prioritize ethical considerations when developing AI technologies.

• Example...read more

Freezing of model refers to fixing the weights of certain layers during training to prevent further updates.

• Freezing certain layers means their weights will not be updated during training

• Helps in transfer learning by keeping pre-trained layers intact

• Prevents overfitting on small datasets

• To prevent freezing, only freeze layers that are already trained on similar data

• Use a lower learning rate for frozen layers to prevent

Developed a predictive model to forecast customer churn for a telecommunications company.

• Collected and cleaned customer data including usage patterns and demographics.

• Used machine learning algorithms such as logistic regression and random forest to build the predictive model.

• Evaluated the model's performance using metrics like accuracy, precision, and recall.

• Implemented the model into the company's CRM system to identi...read more

Implement a stack using the given structure.

• Create a struct with an array to store the stack elements and an index to keep track of the top element

• Implement functions like push, pop, and peek to manipulate the stack

• Ensure to handle stack overflow and underflow cases

Concurrency is the ability to run multiple tasks simultaneously, achieving parallelism.

• Go uses goroutines to achieve concurrency

• Goroutines are lightweight threads managed by the Go runtime

• Concurrency in Go is achieved using channels for communication between goroutines

Types of channels in Go and their use cases

• Buffered channels: Allow multiple senders to send data without blocking until the buffer is full

• Unbuffered channels: Synchronize goroutines by blocking sender until receiver is ready

• Bidirectional channels: Allow both sending and receiving data

• Receive-only channels: Restrict channel to only receive data

• Send-only channels: Restrict channel to only send data

To downgrade an application in Kubernetes/Openshift, you can rollback to a previous version using deployment history or by updating the image tag.

• Use kubectl rollout undo command to rollback to a previous deployment

• Update the image tag in the deployment configuration to point to an older version

• Use Helm to manage application versions and rollback if needed

ARP stands for Address Resolution Protocol, used to map IP addresses to MAC addresses. DHCP stands for Dynamic Host Configuration Protocol, used to assign IP addresses to devices on a network.

• ARP is used to find the MAC address of a device based on its IP address

• DHCP is used to automatically assign IP addresses to devices on a network

• ARP is a layer 2 protocol, while DHCP is a layer 3 protocol

• Example: When a device want...read more
