If you're asked, "Can you provide details for the assessment?", the answer depends on the context.
For a Job Interview Assessment at Wipro:
"The assessment typically includes sections on aptitude (quantitative, logical reasoning, verbal ability), coding (for technical roles), and sometimes an essay or business communication test. The coding section usually involves problem-solving in languages like Python, Java, or C++. The difficulty level varies based on the role, and candidates are evaluated on accuracy, efficiency, and problem-solving skills."
For an Employee Performance Assessment:
"The assessment process at Wipro evaluates employees based on key performance indicators (KPIs), project contributions, skill development, and feedback from peers and managers. It helps in career growth, identifying training needs, and aligning with organizational goals."

Interview Preparation Tips
Then after putting my lot of time and efforts when finally it comes to release the offer, then they stop picking up the calls and stop responding and the final excuses which I got from them for not releasing the offer is that their software will not allow them to release any offer which is more that 2 days of joining.
Such a pathetic company who even don't know that atleast if you are not releasing the offer, it's your duty to atleast tell the person that either they are not able to provide the compensation as discussed or they are looking parallelly for someone who can settle in less compensation.
Due to all this I have wasted almost my 3-4 weeks of time expecting that I will receive the offer, and didn't focus on other organisations which was ready to provide slightly lower than this.
Hence it's a total scam which is going here suggesting not to get trapped otherwise you will not only waste your time but also other good opportunities as well.
It's a total boycott for me, expecting the same from your end as well, so that they will understand that playing with someone's job is not a joke.

- Q3. What is currying in js?
- Ans.
Currying is a technique in functional programming where a function with multiple arguments is transformed into a sequence of nested functions, each taking a single argument.
Currying helps in creating reusable functions and partial application.
It allows you to create new functions by fixing some parameters of an existing function.
Example: const add = (a) => (b) => a + b; add(2)(3) will return 5.
- Q4. What is the difference between Map and Filter?
- Ans.
Map is used to transform each element of an array, while Filter is used to select elements based on a condition.
Map returns a new array with the same length as the original array, but with each element transformed based on a provided function.
Filter returns a new array with only the elements that pass a provided condition function.
Example for Map: [1, 2, 3].map(num => num * 2) will result in [2, 4, 6].
Example for Fi...
- Q5. What is the difference between Map and ForEach?

- Ans.
Authentication verifies the identity of a user, while authorization determines the user's access rights.

Authentication precedes authorization in the security process.
