Whiz.AI is a startup.
Note :- In the start its people will be saying that they are open for the salary, plus they may be
claiming that it is a brand & you will be getting lot of opportunity to grow both technically
& financially. They will be trying to attract you saying they use AI & ML etc.
But the reality will be different for the salary part & for technical part, I believe the reality
is also quite opposite. Plus I also doubt about its growth as after 4 years, still they have
not touched 100 as employee count, but they proudly say that have presence in other
countries also. HR person(from US), with whom I had discussion for salary, was very
rude & unprofessional.
So take your own call to try for or join this organisation.
I got the call from its recruiter & then next day I had a 30 mins technical discussion where I was asked very basic questions to code for.
After 1 week I got the call again for the next round which was taken by its architect & he also asked very basic questions to code for, in which I fumbled.
Below are those parts where I fumbled in both the rounds -
Round 1 : In one question I was creating the map & depending on some condition I was
picking the key-value pair from that map & was putting that in new map.
For this, I was asked how can do the same without creating a new map, means I
was just required to remove all those pairs from the map which I don't need based
on that condition & it was logical also. Here I made the mistake & I was not able to
solve it.
Point to remember here is that, you shouldn't use internal iterator while iterating
through its keys, fetch the iterator from its key set then remove the keys as per the
condition from that iterator & the map will also be changed.
Remember, enumerator doesn't allow any change but iterator allows delete
operation while iterating.
This round took 30 mins.
Round 2 : During this round few basic theoratical questions were asked along with below
questions to code for -
1) Write the code showing the deadlock scenario.
2) Write the code to find the max number in the given array of double.
For (2), I used Double.MIN_VALUE to start with & it was a mistake here, as it gives
the smallest positive nonzero value of type double & it failed if the values in array are
negative & I kept wondering without focusing on the documented words for
MIN_VALUE.
And it took time further to write the correct code for this using other traditional way.
Or you can use Functional way to find the max from the given array.
3) Write the code to find the largest & second largest in the given array of double.
Below is the code which one try to play with deadlock scenarios & can try his/her ideas also
to check the deadlock scenario.
If you have other way to code for deadlock, then please comment also, so that others also
can check.
For other questions also, please comment your way of code...
