10+ Prannath Parnami Institute of Management & Technology Interview Questions and Answers

The function checks if any two intervals overlap with each other.

• Iterate through the intervals and compare the end time of one interval with the start time of the next interval.

• If the end time is greater than or equal to the start time, the intervals overlap.

• Return true if any overlapping intervals are found, otherwise return false.

The task is to find the length of the longest common subsequence between two given strings.

• A subsequence is a string that can be derived from another string by deleting some or no characters without changing the order of the remaining characters.

• We can solve this problem using dynamic programming.

• Create a 2D array to store the lengths of the longest common subsequences for all possible prefixes of the two strings.

• Iterate through the strings and fill the array based on the fol...read more

The task is to find the order of characters in an alien language given a sorted dictionary.

• The order of characters can be determined by comparing adjacent words in the dictionary.

• Create a graph where each character is a node and there is a directed edge from character A to character B if A comes before B in the alien language.

• Perform a topological sort on the graph to get the order of characters.

The task is to create a new string by repeatedly taking the smallest character from the first 'K' characters of the given string and appending it to the new string.

• Iterate through the given string in chunks of size 'K'

• Find the smallest character in each chunk and append it to the new string

• If there are characters remaining in the string, sort them and append to the new string

• Repeat the above steps until the original string is empty

Reverse a linked list using iterative approach

• Initialize three pointers: prev = null, current = head, next = null

• Iterate through the linked list, updating pointers as follows: next = current.next, current.next = prev, prev = current, current = next

• Update the head to point to the new head (prev)

The workflow process for preparing erection drawings involves gathering project information, creating initial sketches, obtaining approvals, and finalizing detailed drawings.

• Gather project information such as architectural plans, structural drawings, and specifications

• Create initial sketches to visualize the design concept

• Obtain approvals from clients, architects, and engineers before proceeding

• Finalize detailed drawings with accurate dimensions, annotations, and material spe...read more

OOPs stands for Object-Oriented Programming. It is a programming paradigm based on the concept of objects.

• OOPs focuses on creating objects that contain both data and methods to manipulate that data.

• It allows for reusability, modularity, and flexibility in code.

• Key principles of OOPs include encapsulation, inheritance, and polymorphism.

• Examples of OOPs languages include Java, C++, and Python.

Dyn11 is a vector group notation used in transformers to indicate the phase displacement between primary and secondary windings.

• Dyn11 is a three-phase transformer with the primary winding connected in delta and the secondary winding connected in star with neutral grounded.

• The phase displacement between primary and secondary windings is 330 degrees.

• Dyn11 is commonly used in Europe and Asia for distribution transformers.

• Other vector group notations include Yyn0, Yd1, Dd0, etc.

Virtual destructor is used to ensure proper destruction of derived class objects when deleted through a base class pointer.

• Virtual destructor is declared in the base class with the 'virtual' keyword.

• It allows the destructor of the derived class to be called when an object is deleted through a base class pointer.

• Without a virtual destructor, only the base class destructor would be called, leading to memory leaks or undefined behavior.

Maintaining proper project schedule involves effective planning, monitoring, and communication.

• Create a detailed project schedule with clear milestones and deadlines

• Regularly monitor progress and adjust schedule as needed

• Communicate with team members to ensure everyone is aware of their tasks and deadlines

• Use project management tools to track progress and identify potential delays

• Address any issues or roadblocks promptly to prevent schedule slippage

There are 7 clauses in ISO 9001:2015.

• ISO 9001:2015 has 7 clauses that outline the requirements for a quality management system.

• These clauses cover areas such as context of the organization, leadership, planning, support, operation, performance evaluation, and improvement.

• For example, Clause 4 focuses on understanding the organization and its context, while Clause 8 addresses operation.

• Each clause is essential for ensuring the effectiveness of the quality management system.

Structural methodology involves analyzing, designing, and testing structures to ensure they meet safety and performance requirements.

• Analyze the structural requirements and constraints of the project

• Design the structure using appropriate materials and techniques

• Perform simulations and tests to validate the design

• Iterate on the design based on test results and feedback

• Document the entire process for future reference

Commonly used weld symbols include fillet weld, groove weld, plug weld, spot weld, and seam weld.

• Fillet weld symbol is a right-angled triangle

• Groove weld symbol is a square or rectangle

• Plug weld symbol is a small circle

• Spot weld symbol is a small circle with a crosshair

• Seam weld symbol is two parallel lines

Meshing standards ensure quality of simulation results.

• Meshing standards define the size and shape of elements in a simulation model.

• Quality criteria ensure that the mesh is accurate and reliable.

• Mesh quality can be evaluated using metrics such as aspect ratio and skewness.

• Standards and criteria vary depending on the type of simulation and the desired level of accuracy.

• Examples of meshing standards include ISO 10303-11 and ASTM E2149.

PMP certification is definitely an added advantage for a Senior Project Engineer.

• PMP certification demonstrates advanced project management skills and knowledge.

• It shows commitment to professional development and continuous learning.

• Employers often prefer candidates with PMP certification for senior roles.

• Having PMP certification can lead to higher salary and career advancement opportunities.
