I applied via Walk-in and was interviewed in Jan 2024. There were 2 interview rounds.
(2 Questions)
- Q1. Which is muteable in python? (list,tuple,string,int,float)
- Ans.
Lists are mutable in Python.
Lists can be modified after creation, allowing for addition, removal, and modification of elements.
Tuples, strings, integers, and floats are immutable in Python.
Example: list_example = [1, 2, 3]; list_example[1] = 5 # modifies the list element at index 1 to 5.
- Q2. Str="Hello world" print(str[4:8] )
- Ans.
The code will print 'o wo', which is the substring of 'Hello world' starting from index 4 up to index 7.
The slicing operation str[4:8] extracts characters from index 4 to index 7 (exclusive) from the string 'Hello world'.
The index 4 corresponds to the character 'o' and index 7 corresponds to the character 'd'.
Therefore, the output of print(str[4:8]) will be 'o wo'.

New Job, Higher Pay, Now I’m Feeling AwkwardI’ve been at my new job for about six months now, and everything’s been going great! I’m getting positive feedback from my manager, and I get along well with the team. The thing is, when I started, my salary offer ended up being much higher than the initial number discussed during my interview. I didn’t negotiate and just accepted the offer. So, fast forward to happy hour with the team, and the topic of salary comes up. I, unfortunately, shared what I’m making, and let’s just say... it didn’t sit well with the others who have been on the team for years and make less than me. They weren’t mad at me, but now I’m feeling a bit uncomfortable and unsure how to handle this situation. Has anyone had something like this happen? How did you deal with it?
