10+ Eversendai Interview Questions and Answers

Aircraft engines work by sucking in air, compressing it, adding fuel, igniting it, and expelling the exhaust gases to create thrust.

• Air is sucked in through the front of the engine by the fan blades

• The compressor squeezes the air to increase its pressure

• Fuel is added and ignited in the combustion chamber

• The hot exhaust gases are expelled out the back of the engine, creating thrust

• Different types of engines include turbojet, turboprop, and turbofan

I have experience in conducting statistical analysis, data modeling, and forecasting.

• Proficient in statistical software such as R, Python, and SPSS

• Experience in analyzing large datasets and identifying trends

• Skilled in creating data visualizations to communicate findings

• Knowledge of regression analysis, hypothesis testing, and predictive modeling

IC engines work by converting fuel into mechanical energy through combustion within the engine.

• Fuel is mixed with air and ignited in the combustion chamber

• The resulting explosion pushes a piston, which turns a crankshaft

• The crankshaft converts the linear motion of the piston into rotational motion

• The rotational motion is used to power the vehicle or machinery

• Examples include gasoline engines, diesel engines, and natural gas engines

Java performance management techniques involve optimizing code, memory usage, and resource allocation.

• Use efficient data structures and algorithms to improve performance.

• Optimize code by reducing unnecessary loops, avoiding excessive object creation, and minimizing memory usage.

• Utilize profiling tools like JVisualVM or YourKit to identify performance bottlenecks.

• Implement caching mechanisms to reduce redundant computations and database queries.

• Consider using multithreading an...read more

List is mutable, ordered collection of items while tuple is immutable, ordered collection of items in Python.

• List is defined using square brackets [] while tuple is defined using parentheses ().

• Elements in a list can be changed or modified while elements in a tuple cannot be changed.

• Lists are typically used for collections of similar items while tuples are used for fixed collections of items.

• Example: list_example = [1, 2, 3] and tuple_example = (4, 5, 6)

Tuple is immutable, list is mutable in Python.

• Tuple elements cannot be changed once assigned, while list elements can be modified.

• Tuple uses parentheses () and list uses square brackets [] for declaration.

• Example: tuple_example = (1, 2, 3) vs list_example = [1, 2, 3]

Back propagation is a method used to train neural networks by adjusting the weights based on the error calculated during the forward pass.

• Back propagation involves calculating the error between the predicted output and the actual output.

• The error is then propagated backwards through the network to adjust the weights using gradient descent.

• This process is repeated iteratively until the network's performance improves.

• Example: If a neural network is trained to recognize handwrit...read more

Regularisation in random forest helps prevent overfitting by controlling the complexity of the model.

• Regularisation in random forest is achieved by limiting the depth of the trees in the forest.

• It helps prevent overfitting by reducing the complexity of the model and improving generalization.

• Regularisation parameters like max_depth, min_samples_split, and min_samples_leaf can be tuned to control the complexity of the model.
