[prabhakar]

hi friends,
how are you everybody.hope u people are doing gr8.I had a technical
round from people of wipro last evening and it was a good interview
for about 20 minutes and i am posting the questions they asked me in
the interview. I hope this will help you guys to prepare for your
interviews.

1). Tell me about technical challenges you faced in your recent
assignment?

2). What are the Apex governeor limits?

3). How many triggers can you write in an Apex class?

4). How many records can you fetch using a query min and max?

5). If i have 15 before insert operations and 18 after insert
operations in a trigger will it exceed the governor limits?(the
question is not so clear to me so i skipped it to answer)

6). What are challenges you faced when loading the data into
salesforce?

7). What is Cross object formula and how many levels you can go deep?

8). he gave four operations like
a) Page layouts
b) Validation rule
c) triggers
d) Workflows
What is the order of execution of these four?

9). While deploying a class i got couple of errors one is "testrun
failure" and "test coverage failed" explain these two errors and give
the solution to solve them?

10). What is the current version of API in salesforce? What version
did u used in recent project?

I welcome everybody to give answers to these questions as many as
possible you can answer so that i can prepare for future interviews.

thanks in advance

1). Tell me about technical challenges you faced in your recent
> assignment?

> A: i haven't face any major technical challenges every thing was simple, minor technical will be there in any project, resolution of these challenges it our job.
minor challenges were like this:
modifying: workflow rules, creating new validations, checking the
relationships between two objects.etc

> 2). What are the Apex governeor limits?

> A:this puts the limits to the number of queries processed and give limitations to several other functionality too the

> 3). How many triggers can you write in an Apex class?

> 10

> 4). How many records can you fetch using a query min and max?

> min is 1 max is 200

> 5). If i have 15 before insert operations and 18 after insert

> A:Yes
Total number of DML statements issued (insert, update,upsert, merge,
delete, or database.emptyRecycleBin) <= 20

> 6). What are challenges you faced when loading the data into
> salesforce?

> data loading is a simple process and i have done it quite confidently

> 7). What is Cross object formula and how many levels you can go deep?

> A:Cross-object formulas are formulas that span to related objects and reference merge fields on those objects. Cross-object formulas can reference merge fields from a master ("parent") object if an object is on the detail side of a master-detail relationship, or from another object if a lookup relationship to that object exists on the current object. You can reference fields from objects that are up to five relationships away. Cross-object formulas are available anywhere formulas are used except when creating default values

> A: depending on the scenario the order of execution will change
for manual entry : A.B.D.C
for data loading :C.D.A.B
etc....

A: Test failures – System.AssertEqual or AssertNotEqual calls failed

A code coverage section
This section lists all the classes and triggers in your organization
and the percentage of lines of code in each class and trigger that are
covered by tests. If you click on the coverage percent number, a page
displays, highlighting all the lines of code for that class or trigger
that are covered by tests in blue, as well as highlighting all the
lines of code that are not covered by tests in red. It also lists how
many times a particular line in the class or trigger was executed by
the test.
